002 Wind Calculation On Wall

The document calculates wind loads on the walls of a proposed import-export warehouse building in Haryana, India. It provides details of the building dimensions and wind speed calculations based on IS 875 standards. It then calculates the external wind pressure coefficients and resultant wind loads on each wall and column based on the wind direction. The maximum wind loads are 9.27 kN/m on the windward columns and 3.31 kN/m on the leeward columns.

Wind Load Calculation for Wall

Maximum wind speed is considered for the design


Basic Wind Speed, Vb = 47 m/s
Probability Factor, k1 = 1
Terrain type = Category-1,
Class of Building = Class C
Terrain, Height & Structure size factor k2 = 0.99 (h =30m)
Topographical Factor, k3 = 1.00
Design wind speed Vz =Vbxk1xk2xk3 = 47*1*0.99*1
= 46.53 m/s
Design wind pressure p=0.6xVz2 = 0.6*46.53^2
= 1.32 kN/m²

Length of the building, l = 61.25 m


Width of the building, w = 35.00 m
Height of the building, h = 7.75 m
Height ratio 1/2< h/w <= 3/2 h /w = 0.22
Plan ratio 3/2 < l/w <= 4 l /w = 1.75

Pressure co- efficient : [ Refer IS : 875 ( part III) - 1987, table 4]


Z-direction: (Wind at 0 degree)
External pressure co.effe in windward side A 0.70
External pressure co.effe in leeward side B 0.25
