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

QUESTION 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

ANSWER 1

AIM

To generate manual wind loading in the design report based IS code per the following input

Basic wind speed= 39m/s

Terrain category = 2

PROCEDURE

First, calculate the load combination

RESULT

Calculations is done for the wall panel

QUESTION 2

Based on the above calculation apply the loadings on the model

ANSWER 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 loadcase and add new load case

• Now as per value apply the load
• Frame 1= Wind + y + cpi = 0.253KN/m^2

• Apply load on frame 5= Wind + y + cpi = -0.951KN/m^2
• Negative value means wind acting away from the wind panel

• Apply load on face 1 = Wind + y + cpi = 1.52KN/m^2

• Apply load on face 5 = Wind + y + cpi = 0.317KN/m^2

• Apply load on face C = Wind + y + cpi = 1.394KN/m^2

• Apply load on face D = Wind + y + cpi = 0.127KN/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=-0.253KN/m^2

• Apply load on Frame 1= wind-y+cpi=0.951KN/m^2

• Apply load on Frame 5= wind-y+cpi=-1.521KN/m^2

• Apply load on Frame 1= wind-y+cpi=-0.317KN/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=0.127KN/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=-1.204KN/m^2

• Apply load on Frame 2= wind+y+cpi=0.063KN/m^2

• Roof XY
• Apply load on frame 1 = wind+y+cpi=0KN/m^2
• Roof PQ
• Apply load on frame 1 = wind+y+cpi=1.204KN/m^2

• Apply load on frame 1 = wind-y-cpi=0.063KN/m^2 on roof PR

• Apply load on frame 2 of roof XY = wind-y+cpi=1.267KN/m^2

• Apply load on frame 2 of roof XY = wind-y+cpi=0KN/m^2

RESULT

QUESTION 3

On a separate model generate wind loading using wind wizard

ANSWER 3

AIM

On a separate model generate wind loading using wind wizard

PROCEDURE

• Open the file
• Open load cases in the 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
