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

1)

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)

Aim - 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 loadcases 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)

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 -
