DESIGN ANALYSIS OF COLUMN NO. 707 Factored load, Puz = 2459.7 KNColumn size 500mm x 500mmUnsupported length, L0 = 3mGrade of steel = 415 N/mm2
Grade of concrete, = 20 N/mm2
Clear cover = 40 mm Calculation of slenderness ratio: As per code IS456:2000, Slenderness ratio should be less than 12
Hence, it is short column.
Calculation of minimum eccentricity: As per code IS456:2000
Therefore, additional moment can be neglected.Calculation of area of steel required for longitudinal reinforcement: As per code IS456:2000;
Therefore, = 1701mm2
0.8% steel = 0.8*500*500/100 =2000mm2
As per code IS456:2000, minimum reinforcement required for column design is 0.8% of concrete area. Hence, we should design the column for minimum reinforcement required. As per code IS456:2000, minimum reinforcement required for column design is 0.8% of concrete area.Therefore, As =2000mm2
Use 16 mm steel bar as main reinforcement.Area of 16mm steel bar = 201 mm2.Therefore, No. of bars = 2000/201 = 9.9 Provide 10-16mm steel bar as longitudinal/main reinforcement steel.
Calculation for tie reinforcement:
As per code IS456:2000;
Diameter of tie bar ≥ diameter of bar used as main reinforcement/4
Therefore, diameter of tie bar ≥ 16/4 = 4mm
Therefore, use 8mm as tie reinforcement.
Spacing for tie reinforcement:
As per code IS456:2000;
Spacing:
(1) Least of lateral dimension of the compression member = 500mm
(2) 16*(smallest diameter of main the longitudinal reinforcement) = 16*(16) = 256mm
(3) 300mm
Whichever is the least has to be provided.
Hence, provide 8mm diameter of tie reinforcement @250mm c/c.

CALCULATION FOR MZ = -56.53 kNm AT L = 4.225m(x/d) ratio required for given bending moment:
Area of steel required
Hence, provide 5-12mm reinforcement steel in tension side at L = 4.2m where Mz = -47.53 kN.m Note that the tension side is at the top of the beam.CALCULATION FOR MZ = -34.54 kNm AT L = 0m(x/d) ratio required for given bending moment:
Area of steel required
Hence, provide 3-12mm reinforcement steel in tension side at L = 0m where Mz = -34.54 kN.mNote that the tension side is at the top of the beam.
CALCULATION FOR MZ = 65.9kNm AT L = 2.1m(x/d) ratio required for given bending moment:
Area of steel required
Hence, provide 5-12mm reinforcement steel in tension side at L = 2.1m where Mz = 20.38 kN.mNote that the tension side is at the bottom of the beam.
Calculation for Distribution bars:
As per IS456:2000;
Area required for distribution = 0.12b*D/100
Therefore, area to be provided for distribution steel = 0.12*200*400/100 = 96 mm2
Use 8mm (2L) bar as distribution steel.
Spacing provided for distribution steel= 100.5*200/96 = 209.4 mm
Provide at the end of Beam
8mm (2L) distribution steel @200mm c/c.
And at the mid of spam of Beam
8mm (2L) distribution steel @220mm c/c.

Design of Slab (Hand Calculation)
Design of Slab Dimensions = 4 X 6 m2
Effective length = clear span + depth = 4.15 mFloor finish = 1 KN/m2
Live load = 4 Kn/m2
Span to depth ratio = 30 Depth = (4.15/30) = 127.5 mm
Assume a depth of 150 mmProvide 10ϕ bars
d = 150 -15 -5 = 130mmDead Load = 2.5*0.15 + 1 =4.75 Kn/m2
Live Load = 2 Kn/m2
Design Load = 1.5*(4.25+2) = 10.125Kn/m2
Since the ratio of longer side by shorter side is 1.5 design it as a one way slab
α y = 0.037α x = 0.053
We get respective moments as Mx = 8.568KnMMy = 5.994KnM
d = √(Mu/0.138FckbD) =49mm < 130
Longitudinal Reinforcementsx/d = 1.2- √(1.44 – (6.6Mu/fckbD2))
