To calculate wind load for industrial steel structures and to apply it by using TSD
AIM:
Generate manual wind loading in the design report based IS code as per the following input
Procedure:
Given:
Basic wind speed = 39m/s
Terrain category 2
Based on the above calculations
Vb 39 m/s
terrain category 2
probable design life of structure 50 years class of structure A
L =greater horizontal dist. =18
wall ratios
w lesser horizontal dist. =18
l/w =1
h height of structure =12
h/w =0.666666667
width of frame= 7.2
k3 topography factor= 1
k1 Risk co-efficient= 1
Height up to 10m
k2 =1
k4 =1.15
Vz ,design wind speed =44.85
Pz ,design wind pressure =1.2069135 =Vz*k1*k2*k3*k4/1000

In Model,
Add the load case as cpi+, cpi- In y direction
Go to the respective frame
Select area load ad Wy+ci load case 0.233
Input the respective value from the calculations above
Similarly Wy-ci 1.44
Follow this procedure for all the wind panels

Result:
Generation of manual wind loading in the design report based IS code as per the following input was done
Aim:
in model generate wind loading using wind wizard
Procedure:
In load ta click on the wind wizard option
Add wind speed 39
Terri category 2
Fetch distance 10m
Topography none
next and finish
Define wind loadcases
And check all the panels are I the same direction
Result:
model is generated for wind loading using wind wizard
