A. EXPLANATORY NOTES

1 GENERAL

This publication is a design guide to BS 5950:Part 1:1990 Design Code, using locally

produced hot rolled sections.

1.1 Material

The structural components referred to in this design guide are of weldable structural

steels to BS 4360.

1.2 Sections

The structural sections referred to in this design guide are produced to the following

specifications:

JIS G 3192:1994

1.3 Dimensional Units

The dimensions are given in millimetres (mm).

1.4 Property Units

Generally the centimetre (cm) is used for the calculated properties but for the surface

areas and for the warping constant (H), the metre (m) and the decimetre (dm)

respectively are used.

Note: 1 dm = 0.1 m = 100 mm

1 dm6 = 1 x 10-6m6 = 1 x 1012 mm6

A-2

1.5 Mass and force units

The units used are the kilogram (kg), the Newton (N) and the metre per second per

second (m/s2) so that 1 N = 1 kg x 1 m/s2. For convenience a standard value of the

acceleration due to gravity has been generally accepted as 9.80665 m/s2. Thus the

force exerted by 1 kg under the action of gravity is 9.80665 N and the force exerted

by 1 tonne (1000 kg) is 9.80665 kilonewtons (kN).

2 DIMENSIONS OF SECTIONS

2.1 Masses

The masses per metre have been calculated assuming that the density of steel is 7850

kg/m3.

In all cases, the tabulated masses are for the steel section alone and no allowance has

been made for connecting material or fittings.

2.2 Ratios of Local Buckling

The ratios of flange outstand to thickness (b/T) and the web depth to thickness (d/t)

are given for H and channel sections. They have been calculated using the dimensions

specified in Figure 3 of BS 5950: Part 1 and are use when element end section class

are being checked to the limits given in Table 7 of BS 5950: Part 1.

2.3 Dimensions for detailing

The dimensions C, N and n have the meanings given in the Figures at the head of the

Tables and have been calculated as follows.

3 SECTION PROPERTIES

3.1 General

All section properties have been accurately calculated. They have been calculated

from the metric dimensions given in the appropriate standards (see 1.2)

3.2 For H-Section, Joists and Channels

3.2.1 Second moment of area (I)

The second moment of area of the section, often referred to as moment of inertia, has

been calculated taking into account all tapers, radii and fillets of the sections.

3.2.2 Radius of gyration ( r )

The radius of gyration is a parameter used in buckling calculation and is derived as

follows:

r = [ I / A]1/2

where A is the cross-sectional area.

3.2.3 Elastic modulus (Z)

The elastic modulus is used to calculate the moment capacity based on the design

strength of the section or the stress at the extreme fibre of the section from a known

moment. It is derived as follows:

Z = I / y

where y is the distance to the extreme fibre of the section from the elastic neutral axis.

A-5

3.2.4 Buckling parameter (u) and torsional index (x)

The buckling parameter and torsional index used in buckling calculation are derived

as follows:

a) For bisymmetric flanged sections and flanged sections symmetrical about the

minor axis (H and Joists sections):

where Sx is the plastic modulus about the major axis

γ = −[ / ]1 I Iy x

Ix is the second moment area about the major axis

Iy is the second moment area about the minor axis

A is the cross sectional area

h is the distance between shear centres of flanges (for T section, h is the

distance between the shear centre of flanges and the toe of web.

H is the warping constant

J is the torsion constant

A-6

3.2.5 Warping Constant (H) and torsion constant (J)

The warping constant for H-section, Joists and channel sections are calculated using

the formulae given in the SCI Publication (P057) Design of Members Subject to

Combined Bending and Torsion.

3.2.6 Plastic Modulus (S)

The full plastic moduli about both principal axes are tabulated for all section.

The reduced plastic moduli under axial load are tabulated for both principal axis for

all sections except angle sections, for which BS 5950 requires design using the elastic

modulus.

When a section is loaded to full plasticity by a combination of bending and axial

compression about the major axis, the neutral axis shifts and may be located either in

the web or the tension flange depending on the relative values of bending and axial

compression. Formulae giving the reduced plastic modulus under combined loading

have to be used, which use a parameter “n” as follows:

n = F (this shown in the member capacity tables as F/Pz)

A py

where F is the factored axial load

A is the cross-sectional area

py is the design strength of the steel

For each section there is a “change” value of n.

A-7

(a) H-Sections

If the value of “n” calculated is less than the change value the neutral axis is the web

and the formula for the lower values of “n” must be used. If “n” is greater than the

change value, the neutral axis lies in the tension flange and the formula for higher

values of “n” must be used. The same principal apply when the sections are loaded

axially and bent about the minor axis, lower and higher values of “n” indicating that

the neutral axis lies inside or outside the web respectively.

Major axis bending:

If the value of ‘n’ calculated is less than the lower change value ( n1 ), the neutral axisis in the web and the formula for lower values of ‘n’ must be used. If ‘n’ is greaterthan the higher change value ( n2 ), the neutral axis lies in the part of the tensionflange that is not tapered and the formula for higher values of ‘n’ must be used. If thevalue of ‘n’ calculated lies between the lower change value ( n1) and the higher changevalue ( n2 ). The neutral axis lies in the tapered part of the flange and then a linearinterpolation between the two formulae is used to calculate the reduced plasticmodulus.

c) Channels

The reduced plastic modulus of channels bending about the minor axis depends onwhether the stresses induce by the loading are the same or of opposite kind towards ofthe back channel, any moment due to eccentricity of load being assessed relative tothe centroidal axis. Where the stresses are of the same kind they cause an initial riseof minor axis moment capacity when lower values of ‘n’ apply.

4 MEMBER CAPACITY TABLES

4.1 Compression Members : H- Section, Joists and Channels subject to axial compression

The value of compressive resistance Pcx and Pcy for buckling about the two principalaxes have been based on:

A-10

a) The effective length ( LE) given at the head of the tableb) The slenderness λ is based on:

λ = LE / ry and LE / ry

The values of compression resistance can be calculated using the Perry Strut Formula

Pc = AgPc

Where Ag the gross sectional area and Pc has been obtained using a

Robertson constant of 5.5

λ is the slendernessλo is the limiting slenderness, which should be taken as

0.2 (yPE2π )1/2

4.2 Bending : H section, Joists and Channels subject to Bending

The moment capacity Mcx has been calculated assuming that the shear load is low andis given by:

Mcx = py Sx ≤ 1.2 pyZx for plastic and compact sectionsand Mcx = pyZx for semi- compact sections

Where the shear load is high the value should be checked and reduced if necessary.

The sections classification has been given but it should be noted that thisclassification applies to members subject to bending about x-x axis only.

The buckling resistance moments Mb have been calculated for the effective lengths LEgiven at the head of the tables:

Mb = pbSx

pb has been obtained for particular values of λLT = η µ ν λ

whereη is slenderness correction factor taken as 0.4,0.6,0.8 and 1.0λ is the slenderness = LE/ ry

µ and ν are defined in code

4.3 Bending : H-Sections, Joists and Channels: bearing, buckling and shear

values for unstiffened webs

A-12

Values have been calculated as follows:

a) Bearing. The capacity of the unstiffened web is given by

Pcrip = (b1 + n2) t pyw

where

b1 is the stiff bearing length

n2 is the length obtained by dispersion through the flange to the

web connection at a slope 1 : 2.5 to the plane of the flange.

t is the thickness of the web

pyw is the design strength of the web

Bearing factors C1, C2 and C3 are derived as follows:

(i) Bearing factor C1 is the portion of n2tpyw due to the beam alone

i.e C1 = 2.5 [(H - d)/2] t pyw for ending bearing and twice this value for

members continuous over bearing

where D is the depth of the section

d is the depth between fillets

(ii) Bearing factor C2 is equal tpyw and must be multiplied by b1 to give the stiff

bearing contribution. b1 is taken to be stiff bearing length neglecting the

flange plate component.

(iii) Bearing factor C3 is the portion of n2tpyw due to any flange plate which may

be present and is equal to 2.5tpyw for end bearing and twice this value for

members continuous over bearing, assuming that the flange plate is

continuously welded. Where the flange plate is not continuously welded.

Where the flange plate is not continuously welded, the value of C3 should be

taken as equal to tpyw hence the value of C3 given in the tables should be

divided by 2.5.

A-13

C3 must be multiplied by the thickness of the flange plate to obtain the

flange plate contribution.

b) Buckling. The buckling resistance of the unstiffened web is given by

Pw = (b1 + n1)tpc

where b1 is the stiff bearing length

n1 is the length obtained by dispersion at 45o through half

the depth of the section

pc is the compressive strength assuming a slenderness of

web of 2.5d/t1 and using the appropriate compressive

strength Table

Buckling factors C1, C2 and C3 are derived as follows;

(i) Buckling factor C1 is the portion of n1tpc due to the beam alone

i.e C1=(H/2)tpc for end bearing

and twice this value for members continuous over bearing.

Buckling factor C2 is equal to tpc and must be multiplied by b1 to give the

stiff bearing contribution.

ii) Buckling factor C3 is the portion of n1tpc due to any flange plate which may be

present and is equal to tpc for end bearing and twice this value for members

continuous over bearing.

iii) C3 must be multiplied by the thickness of the flange plate to obtain the flange

plate contribution.

c) Shear . The shear value of the section is given by

Pv = 0.6 pyt1H

A-14

4.4 Axial Load and Bending :H-section, Joists and Channels subject to axial

load and bending.

Generally members subject to axial compression and bending should be checked for

local capacity (cl . 4.8.3.2) and overall buckling ( cl.4.8.3.3).

Column in sample construction should according with cl.4.7.7.

All the relevant parameter required to evaluate the interaction equations given in the

above clauses have been presented in tabular form as follows:

a) Local capacity check

Values are given in the tables for:

i) Pz = Ag py

ii) F/Pz limits. These are the maximum values of F/Pz up to which the section is

semi compact or compact. The compact limit is given brackets.

iii) Mcx and Mcy. These are the maximum capacities (with the low shear load)

about the major and minor axes respectively. They have been calculated as in

note 6 using Sx and Zx , Sy and Zy as appropriate.

iv) Mrx and Mry. These have determined using plastic moduli given in the section

property tables. For the values of F/Pz at the head of the table. No values are

shown when F/Pz exceed the limit for a compact section.

Mrx = Srx py ≤ Mcx

Mry = Sry py ≤ Mcy

b) Overall buckling Check

A-15

Denotes that the section is slender when fully stressed under axial compression only (

due to the web becoming slender). None of the section listed listed are slender due to

the flanges being slender. Under combined axial compression and moment the section

would be compact or semi compact up to given F/Pz limit. Hence all the values given

in the table have been calculated using the design strength py.

Values are given in the table for:

i) Pz = Agpy

ii) pyZy . this is used for column in the simple construction and in the simplified

approach for overall buckling.

iii) PySy .. For compact sections in the more exact approach this value may be used

for Mcy.

iv) F/Pz limit. This are the maximum value up to which the section is semi-

compact. For value higher then F/Pz limit the local buckling resistance is

exceeded.

v) Pcx and Pcy. These are the compression resistance for buckling about the major

and minor axes respectively. They have been calculated as in note 4.2.

vi) Mb is the buckling resistance moment, calculated as in note 4.3 except that pb

has been obtain for a particular value of λLT = nuvλ assuming n = 1.0 and λ =

LE / ry.

vii) Mbs is the buckling resistance moment for use with columns in simple

construction and has been calculated as for Mb except that pb has been

obtained using a value of λLT = 0.5 λ, where λ = LE/ ry

4.5 Compression members : single angles

The values of compression resistance have been based on :

A-16

a) The length ( L) between intersection of centroidal axes or setting out line of thebolts.

b) The slenderness λ is based on the following :

i) For two or more fasteners in line along the angle at each end or anequivalent welded connection , the slenderness should be taken ass thegreater of :

0.85 Lvv / rvv but ≥ 0.7 Lvv / rvv + 15

1.0 Laa / raa but ≥ 0.7 Laa / raa + 30

0.85 Lbb / rbb but ≥ 0.7 Lbb / rbb + 30

ii) For a single fastener at each end the λ should be taken as the greater of :

1.0 Lvv / rvv but ≥ 0.7 Lvv / rvv + 15

1.0 Laa / raa but ≥ 0.7 Laa / raa + 30

1.0 Lbb / rbb but ≥ 0.7 Lbb / rbb + 30

where rvv is the minimum radius of gyration raa is the radius of gyration about the axis parallel to the connected leg

rbb is the radius of gyration about the axis perpendicular to theconnected leg.

c) Pc = Ag pc

Where pc has been obtained using a Robertson constant 5.5In the case of single fastener at each end, the compression resistance is taken 80%of that for an axially loaded member with the same slenderness.( Note : no values are given for this case ).Slender section are marked * and their resistances have been calculated using areduced design strength.

An angle section is deemed to be slender if, using the notation given in the code,

b/T or d/T > 15∈ or ( b + d ) / T > 23∈

Using the notation in these tables , these requirement become ,

A / t or B / t > 15∈ or ( A + B ) / t > 23∈

In these circumstances the design strength is reduced by the least of the factor

A-17

11 / [( A / t∈ ) – 4 ] ; 11 / [( B / t∈ ) – 4 ] ; 19 / [({ B+A }/ t∈ ) – 4 ] ;

where ∈ = ( 275 / py )1/2

4.6 Compound compression members : two angles

The tables assume the angles are interconnected back to back as recommended in

clause 4.7.13 of the code.

The values of compression resistance are based on the same principles as those forsingle angle compression members except that the slenderness has been taken asfollows:

a) For double angles connected to one side of the gusset or member by two ormore bolts in line along each angle or by an equivalent weld at each end theslenderness λ is the greater of ;

1.0 Lxx / rxx but ≥ 0.7 Lvv / rvv + 30

[ ( 0.85 Lyy / ryy )2 + λc2 ]1/2 but ≥ 1.4 λc

b) For double angle connected to one side of a gusset or member by a single boltin each angle the slenderness λ is the greater of ;


[ ( 1.0Lyy / ryy )2 + λc2 ]1/2 but ≥ 1.4 λc

c) For double angles connected to both sides of gusset or member by two or morebolts in line along each angles the slenderness λ is the greater of;

0.85 Lxx / rxx but ≥ 0.7 Lxx / rxx + 30

[ ( 1.0Lyy / ryy )2 + λc2 ]1/2 but ≥ 1.4 λc

d) For double angles connected to both sides of a gusset or member by single boltin each angle the slenderness λ is the greater of ;


[ ( 1.0Lyy / ryy )2 + λc2 ]1/2 but ≥ 1.4 λc

In case d), the compression resistance is taken as 80% of that for an axially loadedmember with the same slenderness. ( Note: no values are given for this case ).

A-18

In the above , rxx and ryy are the radii of gyration of the double angles about the axes asdescribe in Table 28.

Where λc = Le / rvv but not greater than 50rvv is the minimum radius of gyration of a single angleLe is the length between interconnections.

Le has been determined in such a way that λc is not greater than 50 and L is dividedinto at least three bays.

4.7 Tension members : single angles

The values of tension capacity have been based on :For tension members without lugs an effective area of

a1 + a2 [ 3a1/ { 3a1 + a2 } ]

where a1 is the net sectional area of the connected leg ; i.e. area of leg – area of hole(s)

a2 is the sectional area of the unconnected leg

The area of a leg has been taken as the product of the leg thickness and its lengthminus half the thickness, i.e. t ( A – t/2 ) or t ( B – t/2 ).

4.8 Compound tension members ; two angles

The values of tension capacity have been based on :

a) when the gusset is between the angles, the net areab) when the gusset is on the back of the angles, an effective area of

a1 + a2 [ 5a1/ { 5a1 + a2 } ]

where a1, a2 are as defined in note 4.7
