To calculate wind load for industrial steel structures and to apply it by using TSD

1) Generate manual wind loading in the design report based IS code as per the following input

Basic wind speed = 39m/s

Terrain category 2

AIM : 

• Generate manual wind loading in the design report based IS code as per the following input
• Basic wind speed = 39 m/s
• Terrain category = 2

PROCEDURE :

• First calculate load combination 

RESULT:

• Calculations are done for the wall panel

2) Based on the above calculation apply the loadings on the model

AIM :

• To determine based on the above calculation apply the loading on the model

PROCEDURE :

• Open TEKLA structural software and open week 4 file
• Select load tab, in that select load cases and add new load cases
• Now as per value apply the load
• Frame 1 = Wind+y+cpi = 0.253 kN/m^2
• Apply load on Frame 5 = Wind +y+cpi = -0.951 kN/m^2
• Negative value means wind acting away from the wind panel
• Apply load on face 1 = wind+y-cpi = 1.52 kN/m^2
• Apply load on face 5 = wind+y-cpi =0.317 kN/m62
• Apply load on face C =wind+y+cpi = -1.394 kN/m^2
• Apply load on face D=wind+y-cpi = -0.127 kN/m^2
• Now we will apply load of -y
• All loading will be similar just the direction of wind is changed
• Frame 5 = wind-y+cpi = -0.253 kN/m^2
• Apply load on Frame 1 - wind-y+cpi = 0.951 kN/m^2
• Apply load on Frame 5 = wind-y-cpi = -1.521 kN/m^2
• Apply load on Frame 1 = wind-y-cpi = -0.317 kN/m^2
• Apply load on frame D = wind-y+cpi = 1.394kN/m^2 on global X axis
• Apply load on frame A=wind-y-cpi = 0.127 kN/m^2 on global X axis
• Apply load on face C = wind+y-cpi = 0.317kN/m^2

Now apply wind load on roofs and take roof angle as 25 degree

• From IS 875 part  3 table 3 clause 6.2.3.2 

Now apply roof load on  PQ

• Frame 2 =wind+y+cpi = -1.204 kN/m^2
• Apply load on frame 2= wind+y-cpi = 0.063kN/m^2

Roof XY

• Apply load on frame 1 = wind+y-cpi = 0 kN/m^2

Roof PQ

• Apply load on frame 1= wind -y+cpi = 1.204kN/m^2
• Apply load on frame 1=wind-y-cpi= -0.063 kN/m^2 on roof PR
• Apply load on frame 2 of roof XY = wind -y+cpi = 1.267 kN/m^2
• Apply 0 kN/m^2 on roof XY of frame 2  

RESULT :

3) On a separate model generate wind loading using wind wizard

Aim :

• On a separate model generate wind loading using wind wizard

PROCEDURE :

• Open the file
• Open load cases in load tab
• Delete all load cases and set only default load cases
• On load panel select wind wizard and select the cyclonic effect
• Check all the details of the building like wind speed, height of building affected by wind and also k1 and k2 factor
• Select terrain category as open terrain scattered obstructions
• Fetch distance is 10
• Click next then select topography and then next
• After that, it shows resultant wind pressure 
• Click on Finish 
• Now click on wind load cases
• Now all the loads are applied. and click on validation to check for errors.

RESULT:
