Load Calculation For Simple Pre-fabricated Steel Structure

Load Calculation:

Purlin (200 C 20) = 5.5 Kg/m = 5.5*9.81/(1.2*1000)=0.045 KN/m²; [In general spacing between Purlin is
kept 1200 mm]

Roof Sheet (0.47)=0.47*7850/(1000*.82)=4.5 kg/m² ;
[In a 1m coil 820mm sheet will be found after profile has been made]
=(4.5*9.81)/1000=0.044 KN/m²
= 0.089 KN/m²

Total Load of Purlin & Roof Sheet= (0.045+0.044) KN/m²

Dead Load=0.089*6.1=0.54 KN/m
Live Load=0.57*6.1=3.48 KN/m
L/B=30/30.5=0.98
h/B=6/30.5=0.2
h/L=6/30=0.2

qz= CcC1CzVb²
=47.2X10ˉ⁶X1X0.415X250²=1.224 KN/m²

For,
Wind Ward Wall Pz=CGCpeqz=1.592X0.8X0.224=1.56 KN/m²
Wind Ward Roof Pz=CGCpeqz=1.592X0.81X0.224=‐1.58 KN/m²
Leeward Roof Pz=CGCpeqz=1.592X0.7X0.224=‐1.364 KN/m²
Leeward Wall Pz=CGCpeqz=1.592X0.5X0.224=‐0.974 KN/m²

Force
Windward Wall=6.1X1.56=9.516 KN/m
Windward Roof=6.1X1.56=‐9.628 KN/m
Leeward Roof=6.1X1.364=‐8.32 KN/m
Leeward Wall=6.1X0.974=‐5.943 KN/m
