STEEL BUILDING GRAVITY LOAD CALCULATIONS

 

1. Roof Dead Load

*Purlin wt. + 0.5mm Sheeting wt. + Insulation wt. = 0.10kN/m2

2. Collateral Load = 0.3kN/m2 

3. Components & Cladding Wt. =0.09kN/m2 ON Column

4. Roof Live Load = 1 kN/m2

* Trributary Area = 9 x 16 =144 m2, So, R1 = 0.6,

* F = (1/10)*32= 3.2, So, R2 = 1

* Live Load Reduction Factor Lr = L0 x R1 x R2 =1.0 x 0.6 x 1.0 =0.6kN/m2

5. RCC Floor Dead Load 

R.C.C Wt. + Decking Sheet Wt. + Floor Finish

(0.125*25+0.067+1.2)kN/m2 

=4.4kN/m2 * 1.556m (Spacing of Sub Beam in meter) 

= 6.85kN/m

6. Staircase Dead Load =5kN/m2 

5kN/m2 x 7.772  (Spacing of Sub Beam in meter) 

= 38.86kN/m (devided by 2 for divide load in two frame)

= 38.86 / 2 =19.43kN/m

7. Liftcore Dead Load =5kN/m2

5kN/m2 x 3.815 (Length of Lift)x3.6 (Width of Lift)

= 68.67kN/m /4 (Devided by 4 for applying load on 4 frame)

=17.17kN/m

8. Brick Wall Weight (Unit Weight 18.9 kn/m3)

18.9kN/m3 * 3.05m (Height of the Wall) * 0.25 (Thickness of the wall)

= 14.41kN/m

9. Water Tank RCC Wall Load (Unit Weight 25 kn/m3)

0.25 (Thickness of the Wall) *25* 2.44(Height of the wall)

= 15.25kN/m

10. Floor Live Load = 6kN/m2 

6.0kN/m2 x 1.556 (Spacing of Sub Beam in meter) 

= 9.4 kN/m

11. Partition Wall Load = 1.2kN/m2 (Assumed Load)

1.2kN/m2 * 1.556m = 1.87kN/m

12. Staircase Live Load =5kN/m2 

5kN/m2 x 7.772  (Spacing of Sub Beam in meter) 

= 38.86kN/m (devided by 2 for divide load in two frame)

= 38.86 / 2 

=19.43kN/m

13. Liftcore Live Load =2 Ton

Impact Loaad = 2*1.5 

= 3MT=3000kg =29.43kN/4 =7.36kN/m

14. Water Tank Load 

1. 54368litre = 54.368m3*9.81kN/m3 

= 533.35kN/(15*16.17/10.76)*1.508 =35.68kN/m

2. 40000litre = 40.00m3*9.81kN/m3 

= 392.4kN/(11*16.17/10.76)*1.508  =35.8kN/m

3. 40000litre= 40.000m3*9.81kN/m3 

= 392.4kN/(12.42*14.33/10.76)*1.508 =35.77kN/m

4. 58900litre= 58.90m3*9.81kN/m3 

= 577.81kN/(18.25*14.33/10.76)*1.508 =35.85kN/m
