Design OutlineThe design for this project will adhere to both The Town of Bethlehem and The New

York State Building Codes for Mixed Economic Use. The City of Santa Ana, California has

very clean requirements with regards to the design of hotels, and these requirements will also

be used as a guide in order to provide the most practical hotel design possible. Since the

structural design is not heavily dependent on the exact interior details of this project, things

such as furniture and utility layouts will not be addressed in full detail. The major design

requirements to be focused on will include,

1. Setbacks:

A landscaped setback not less than twenty-feet shall be provided to the extent it abuts a

public or private street or freeway.

2. Building Landscaping:

A five foot minimum landscaped area shall be provided to separate ground floor units

from pedestrian walkways.

3. Drop-off Zones:

Have a covered drop-off zone for guests to load and unload luggage from cars.

4. Pedestrian Walkways:

Must be minimum of eight feet wide

5. Open Space:

1,000 square feet of common space shall be provided at a 50 square feet per guest unit

ratio up to a total of 7,500 square feet.

6. Amenities:

Outdoor and indoor amenities such as an outdoor/ indoor pool, exercise room, or business

center

7.

Conference Rooms:

Minimum of 2,500 square feet of interior floor area at 20 square feet per guest room ratio

8. Lobby:

Minimum of 1,000 square feet of interior shall be devoted to the lobby with a minimum

ceiling height of twelve feet.


5/90

9. Laundry Room:

Shall include one washer and one dryer for every twenty guests

10.Minimum Room Size:

Each guest room shall have a minimum of 220 square feet.

Final DesignAfter consideration of several different footprints, we chose a Y shaped floor plan (Figure

1), with three wings, and one central core. Because the Bethlehem code defines a hotel as a

building with no less than 41 dwelling units, our design has 48, 15 x 28 ft. rooms on floors 2, 3,

and 4. These 3 floors will also contain 1 laundry room each having 3 washers and 3 dryers. The

first floor will be reserved for amenities such as conference rooms, a gym, and a dining room.

The first floor will also host the main lobby, staff offices, the hotel laundry room, storage rooms,

and a kitchen to supply food for the dining room.

In order to keep mobility fluid and safe throughout the building, a staircase will be placed

in each wing, paired with a means of egress. The central core of the building will feature its own

staircase, as well as two elevators to provide handicapped access to the upper levels, with a

machinery service room on the first floor to accommodate elevator repair and maintenance.

In order to accommodate for HVAC, plumbing, and the depth of structural beams and

girders, we are allocating 13 feet between each level, thus leaving 3 feet of overhead space for

M.E.P. and structural systems in the rooms and corridors. However, because building code

requires 11 feet of clearance in the lobby, the ceiling will only be dropped by 1.5 feet, which still

provides adequate space for the structural elements, as well as the HVAC and plumbing.

With regards to HVAC, every guest room will be equipped with an individual AC unitbuilt integral with the wall. This solution keeps costs down, while providing climate control to

each individual room. However, all of the public rooms such as the lobby, hallways, gym, etc.

will receive ventilation from centralized HVAC units on the roof.

For the exterior of the building, we plan on using a brick veneer in order to provide a

visually appealing and durable finish, which is easy to maintain. Another alternative to the

exterior finish still incorporates the use of brick veneer, however, it would only be used for the

first floor, leaving the rest of the faade to be compromised of EIFS, which is cheaper and easier

to install.

Finally, the roof will be designed to accommodate the 2 HVAC units which provide

heating and cooling for the first floor and corridors and common areas for the 3 upper levels.

The roof has also been designed to allow future incorporation of a green roof to help address

sustainability issues.

Preliminary Structural Assessment

Interior Live Loads Concerning the live loads experienced by the structure, the base floor will be considered

public rooms which entails of uniform live load of 100 psf which applies to the rooms

themselves and any corridors that serve them (ASCE Table 4-1)

The 100 psf live load will also be applied to the dining room and restaurant also located

on the base floor (ASCE Table 4-1).

Also located on the base floor will be a kitchen, which will have an estimated uniform

live load of 150 psf (ASCE Table C4-1).

For the hotel laundry room on the base floor, 3 Washers and 3 Dryers will be considered,

whose weights are approximately 8500 lbs each, this value is increased by 20 percent to obtain a

design value of 10,200 lbs as per ASCE 4.6-3.


10/90

10

For the second, third, and fourth floor, a uniform live load of 46 psf for the private guest

rooms (ASCE Table C4-2).

The corridors serving these floors will be 40 psf uniform live load (ASCE Table 4-1).

Rest rooms, which will be located throughout, will have a uniform live load of 60 psf

(ASCE Table C4-1).

Elevator machine room will be taken as a uniform load of 150 psf (ASCE Table C4-1).

Also, reduction in live loads will be applied where applicable, dependent upon the

location of the column and tributary area. The equation to apply live load reduction will be done

in accordance to ASCE 4.7-1:

L = Lo [ 0.25 + (15/ (square root (KLLAT))]

L = reduced live load per ft2

Lo= unreduced live load per ft2

KLL= live load element factor (ASCE Table 4-2)

AT= tributary area carried by column in ft2

Snow LoadsWhen considering the loads placed upon the roof, a flat snow load, pf, was established to be

27.72 psf. This value was derived from equation ASCE 7.3-1:

Pf= 0.7*Ce*Ct*I*Pg

Ce=Exposure Factor (ASCE Table 7-2)

Ct=Thermal Factor (ASCE Table 7-3)

I=Importance Factor (ASCE Table 1.5-2)

Pg=ground snow load (ASCE Fig 7-1).

The actual calculation and values for the aforementioned parameters can be found in the

Appendix sections under Snow Loads heading. It is also important to find drift loads for the

snow caused by the parapet walls and mechanical installations on the roof. For the parapet walls,

the greatest uniform loads calculated was 22.46 psf. The drift loads appears in a triangular

distribution, with 22.46 psf the height of the triangular distribution. This was done using ASCE


11/90

Fig 7.9 for drift snow loads. All pertinent drawings and calculations can be found in the

Appendix section.

Wind LoadsAs pertaining to the loads on the structure caused by wind, it is pertinent to understand how the

values for wind pressures were developed. First, the hotel was classified as a Risk Category:

III structure according to the table 1.5-1 found in ASCE/SEI 7 Minimum Design Loads for

Buildings and Other Structures. This conclusion was reached due to the threat for substantial

loss of human life in case of structural failure. The basic wind speed was established as being

120 mph as per Figure 26.5-1B in ASCE and the remaining wind load parameters were

determined using descriptions provided in chapter 26 ASCE (All wind parameters selected can

be found in Appendix Wind Load Consideration).

The windward wall is expected to experience a pressure of 12.7 psf.

The leeward wall has a pressure of 6.2 psf.

Side wall has a pressure of 10.5 psf.

Roof has a pressure of 24 psf.

Wind Load Consideration includes all pertinent calculations and drawings. The leeward, side

and roof surfaces are expected to experience suction from the resulting wind force so the values

are negative when seen in the calculation sheet.

Rain-On-Snow Surcharge LoadAs per ASCE 77.10 Rain-On-Snow Surcharge Load, it was determined that this load may be

neglected due to the fact that the ground snow load, pg= 40 psf, was greater than 20 psf.

Rain LoadsIn determining the rain load to be applied to the roof, the ASCE 7 provisions given in Chapter 8

and its accompanying commentary in Chapter C8 were used. It was determined that 2 primary 6

diameter roof drains, and 2 secondary 12 wide channel scupper roof drains set 2 above the roof

surface at the end of each of the three wings will provide adequate drainage for the structure.

Based on this drainage system and the 2.5 per hour 100 year return period rain fall the

maximum expected rain load (R) would be equal to 18.1 psf. See appendix for more detail

regarding this calculation.

Seismic LoadsIn determining the seismic loading to be applied to this structure ASCE 7 Chapters 11 and 12

were used, as well as the USGS online DesignMaps site specific report generating application.

First the site specific data was entered in to this online application in order to obtain the initial

coefficients needed to generate the seismic loading condition to be applied for analysis. These

coefficients were generated using the current provisions given in the 2010 ASCE 7 Standard, and

are outline in further detail in the Summary Report and Detailed Reports which can both be

found in the Appendix of this document. Next the Effective Seismic Weight (W) of the building

was estimated using the provisions given in Section 12.7.2 of ASCE 7. Using this weight, the

coefficients generated in the USGS report, and other provisions given in Chapter 12 values for

the lateral forces to be applied the structure at each level and the shear force to be applied to the

columns of the building were generated. See Appendix - A for more detail regarding these

calculations and the USGS Site Specific Reports.

Connections

Throughout the entire structure, there exists only as pin connections in order to reduce the

amount of material that would be necessary if the joints transferred moments. Having solely pin


22/90

22

connections, lateral bracing is then installed to add stiffness to the structure for any lateral loads

that are expected (wind, earthquake).

The pin connections are comprised of gusset plates connected to the beams and girders by

way of shear bolts. In consideration of bolted connections, there exists many modes of failure

one must account for in order to ensure safety and serviceability of the structure. A possible

mode of failure is the shear tear out at the end of the connected element due to the excessive

bearing stress. This consideration results in the equation:

Rn=1.2*Lc*t*Fu

excluded from the shear plane). The threads were included because of the conservative approach

it provides.

Also, it important to check the strength of elements in tension.

Tensile yielding:

Rn=Fy*Ag

(ASCE J4-1)

Fy=yielding stress of material

Ag=Gross cross sectional area of material

Tensile rupture:

Rn=Fu*Ae(ASCE J4-2)

Fu=ultimate stress of material

Ae=Effective area

It is important to note that effective area is the cross-sectional area accounting for the missing

material due to the holes fabricated for the bolts.

All of the strength values will be factored to a design strength as per LRFD steel design

standards:

Design Strength = 0.75*Rn

The design factor is 0.9 for tensile yielding considerations*.

Column Base PlateIn regards to the column connecting to the foundation footings, this will be achieved by

means of a column base plate anchored to the underlying concrete. Columns that are connecting

to the foundation are W12X106 with a peak compressive load of 705 kips. In designing the base

plate dimensions, it is important to consider bearing capacity of the underlying concrete. This

capacity is governed by the equation:

Pp=0.85fcA(AISC J8-1)

Pp=nominal strength of concrete

fc=compressive strength of concrete (4 ksi)


24/90

24

A=bearing area (in2)

When one subsitutes the load (705 kips) in for the nominal strength, one can then solve

for the required area, which in this case was 346 in2. The column plate was then selected to have

dimensions 19X 19 in order to have adequate bearing area (19

2

=361).The sides of the plate outside of the immediate beam area act as a cantilever and the

greatest of those lengths will be taken in the calculation of the thickness of the plate (moment

inceases as length increase for cantilever elements). The equation for plate thickness is:

T=L*Square root ((2*Pu)/(.9*width of plate*length of plate*yielding stress of plate))

(AISC 14-7a)T=thickness (in)

Pu=705 kips

Width of plate=length of plate=19 inYielding stress of plate=36 ksi (A36 steel used for plate)

The resulting thickness for the plate is taken to be 1.75 inches. The column plate used for this

projct will have the dimensions 1.75X 19X 19.

The base plate will be anchored to the foundation using 4-12 anchor rods. This is derived from

equation:

L=(.02*Fy*Db)/(square root(fc)

(ACI 12.3.2)

L=length of anchor rodFy=yielding strength of rods (60 ksi)

Db=diameter of rod

Fc=compressive strength of concrete (4 ksi)

All pertinent calculations and illustration can be seen in appendix titled Column Base Plate.

All connection details are illustrated in the appendix sections under the title Connections.

These connections were modeled using the computer program RISAConnection. The computer

model checks all provisions established by ASCE and an example summary is also included with

the first illustration. Also, there exists hand calculations checking the number of bolts necessary.

The hand calculations are done in relation with Vertical braced Chevron computer model to

ensure that 3 bolts were a satisfactory output for that connection.

Geotechnical Assessment

Soil Profile

The general soil profile of the site consists of about three layers: a thin layer of top soil, a layer

of a silt mix, and shale bedrock. The upper layers of this shale are heavily weathered and contain

expansive pyrite. Our building was placed in the lower left corner of the site map, near the edge

of the wetlands. For this location, borings B-29 to B-32 were used to investigate the soil beneath

the foot print. The elevation across the foot print, from west to east, changes from 380 feet to 400

feet, over a distance of about 300 feet. Water was found in B-32, 5 feet below the surface. See

the attached site map and soil profile for further detail.

Soil Bearing CapacityAccording to the geotechnical report developed by Dente Engineering, the maximum net

allowable soil bearing pressure (qa) is 3000 psi for spread foundations. Using this qagreatly

simplifies the design process. The alternative would be to develop an ultimate bearing capacity

by taking the number of blows on each soil layer, factoring them to N60, find their cohesion and

angle of internal friction and then use a variation of Terzaghis Bearing Capacity formula. Here

the factors for N60 would have to be assumed, as well as the cohesion in the mixed silt layer. The

end result will lead to a qa, which has already been established by Dente.

Final Column Loadings

To be cost effective and make the construction process easy, three column loads were chosen for

footing designs. These select loads are shown below.

# of columns Load range Selected Load

19 < 300 kips 300 kips

26 300 - 500 500 kips

15 >500 705 kips

The three ranges captured almost an equal amount of the 60 columns. The final loads are much

higher than the estimated 150 kips from the preliminary report. With proper preparation of the

site, reasonable footings can still be made.

Excavation and CompactionThe elevation of the lot will be 400 feet, with the retaining wall along the border of the wetlands

dropping to 380 feet. Extensive excavation will be required to meet this elevation and to remove

unsuitable soil and broken shale. It has been determined that the site soil and shale are not

suitable as fill under foundation areas. Shale below the floor subgrade must be replaced with 2 to


28/90

28

4 feet of structural fill to minimize the risk of expansion. Such a cushion will also reduce

differential settlement. The increase in elevation will reduce the presence of groundwater, but the

structure and the retaining wall still must have perimeter foundation drains. Dewatering will be

required during construction and wet soils must be excavated and replaced. Since the building is

on the low side of the elevation, on site soils will change the soil profile drastically. More

important, since the site soil cannot be used under the foundation, a strong fill must be imported.

This fill must be a well graded sand and gravel mix with less than 10 percent fines. Its soil

modulus should be around 8000 ksf. This will provide the support needed for the structure.

The structural fill also must be compacted to 95 percent of its maximum density and within 2

percent of its optimum water content. Such work should be done during a dry season to make

this more feasible. According to the report from Dente Engineering, the soil subgrades should be

compacted by a vibratory drum of ten tons. Sufficient compaction will help to reduce the

potential settlement and strengthen the surrounding soils.

Settlement

The theoretical settlement of a footing at each boring was calculated both elastically and rigidly,

with equations Se = qo*(*B')* (1 - s^2/Es)*Is*If and Se rigid = .93 Se (Das). From the

standard penetration tests conducted during the boring, the soil modulus was found for each

layer, which was then used to find the average modulus under the foundation. Calculating the

shape factor Is and depth factor If involve other factors A0, A1and A2, to calculate its factors F1

and F2. A simplified method is to use tabulated values of F1and F2. Boring 29 had the highest

rigid settlement of 4.6 inches at the center of the footing. Such high settlement will require

excavation, compaction and fill of these weak, moist layers. Settlement calculations must then be

repeated for the new soil conditions. The full calculations are shown in the appendix. Part of the

excavation process will be to add structural fill under the footings and slabs and a new settlement

calculation was done for the max column load by by the same method. By having a solid fill, the

settlement was reduced to about an inch, with almost negligible differential settlement. The new

settlement calculation follows the initial one in the appendix.


29/90

Final Foundation PlanEach column will have its own square spread footing, which will be placed at a depth 4 feet

below the surface. This depth will keep the footing stable and protect from frost penetration.

From the three column loads, a footing was designed. The ACI code was used almost

exclusively. The results of this analysis are shown in the table and diagram below.

The width of the footing was found by the equation: B= col. load / 3ksf. Before the other

dimensions could be found, the load was first factored to get the factored soil pressure, since the

3 ksf already has a safety factor included. Spread footings are design first for shear and then for

flexural resistance. No stirrups are added to the footings, so the concrete itself must be able to

stand the shear. The one-way and two-way shears were calculated using an estimated depth to

steel dimension d, Area/6. This is used to calculate the shear created by the load and the shear

capacity of the footing. From there, the d can be altered to meet the required shear strength, but

not overly excessive. The flexural resistance will have the same reinforcement in either direction

since the footing is square. A one foot width is considered and treated as a beam. The maximum

moment created by the net soil pressure can then be used to calculate the required amount of

steel. This is often express in square inches per foot. The detailed formulas and calculations are

provided in the appendix.

Special ConditionsOur Environmental Engineering consulting group wanted us to put in a retaining wall next to our

plot of land we were given. For the retaining wall, on the backside of the hotel, we decided to

build a cantilever wall. A cantilever wall is the best option here because of how deep we are

digging the foundation of the wall. From the data from the geotechnical report, we only have

information about the soil five feet down. Thus, we can only plan our retaining wall to have a

bottom base of five feet. However, with a cantilever wall, since the base expands backwards so

far into the soil behind the wall, it will give us a more stable retaining wall. A picture of our

design for the cantilever retaining wall can be seen below. This wall will also be the cheapest

option among retaining wall designs.


31/90

31

The elevation in front of the retaining wall is 380 feet. The elevation behind the retaining wall

will be 400 feet. So the retaining wall will have a height of twenty feet. The base will be

fourteen feet, with about four and two thirds feet being out in front of the wall. The thickness of

the base will be two feet, and the thickness of the wall itself will be two feet. There will be about

two feet of the wall underneath the ground. So, this puts the total height of the all at twenty two

feet, but only twenty feet will be exposed. The length of this retaining wall will be about two

hundred feet long until it intersects with the foundation of the hotel. Then it will run for about 30

feet along the side of the foundation.

Failure in a cantilever wall is mostly due to groundwater. The water table can have adverse

affects on a cantilever wall. Here the water table is at about five feet. Since we will only be

going down 2 feet for the base, we will not nut into the water table. So that will not have any

affect here.

Construction and Cost

This retaining wall will be built around borings 29 and 31. The soil data for these two borings isbelow:B-29:The unit weight of the soil in this area was

estimated 110 lb/ft3.The Phi angle of this soil is about 34.83o.The Cohesion of this soil is about 1.0.

B-31:The unit weight of the soil in this area was

estimated 110 lb/ft3.The Phi angle of this soil is about 27.75o.The Cohesion of this soil is about 0.5.

Cantilever wall have an economic height maximum of twenty feet. Our wall just fits that

specification. The cantilever wall frame has an area of seventy six feet. This is the combined

areas of both rectangles that create the wall. This wall is then spanned along 230 feet total.

Inside the wall, there will be a frame made of steel. This will give a mold to pour the concrete

around. The most recent estimates for a cantilever wall online is 135 dollars per square foot.

This would put the total of one foot section of wall at 10,260 dollars. Over 230 feet, this puts

cost at 2,359,800 dollars. This cost includes all excavation, embankment, concrete and rebar

cots.
