Challenge

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:

AIM: Based on the above calculation apply the loadings on the model

PROCEDURE:

Open the Tekla structural software
Open the week 4 file we were working on
Go to load panel->Loadcases->Add new wind load cases
Now for the wind cases, apply the load as per calculated in the Excel sheets above starting from the wind+Y+Cpi condition.
Now as per the values in the sheet,apply the laod .
0.253KN/m2 acting on
Frame 7 Wind+y+Cpi
-0.951KN/m2 acting on
Frame 3 Wind+y+CPi
Here -Ve value means the wind is acting away from the wind panel.
Next load is 1.521KN/m2 acting on
face7 as Wind+Y-Cpi
Now the next load is 0.317KN/m2 on
face3 as Wind+Y-Cpi
Now we will apply wind loads on the Face A&D grids (i.e. face C &D )
Go to the load section in the bottom left and select wind+y+Cpi
Select the area load
Select global axis as X
and enter the value -1.394KN/m2 for Face C
Similarly go to Face D(i.e grid D)
Enter the value of load -0.127KN/m2
select globals axis X and load pattern wind+Y-Cpi
Now we will apply the load of -Y
All loading will be similar just the direction of wind is changed
The load which was acting on the face 7 will act on Face 3 now with opposite sign.
The face A will be considered as Face B and B will be as Face A

//Similarly we apply the Wind X values as above after calculating the wind load in X direction

//For the X direction we use the value of 90degree and put in the values we find according to that

//Similarly we apply load on X direction for roof as we applied in Y

given below is the data required to fill the load for X direction

AIM: On a separate model generate wind loading using wind wizard

PROCEDURE:

Make a copy o the above tekla file
Open the file
Go to load panel->Loadcases
Select the wind load cases you gave in the previous question and delete all.
Only the default load cases will be left.
On load panel->click on a Wind wizard ->Worst case data
Tick the cyclonnic effect
Now check all the basic details of the buildings like basic wind speed,height of bulding affected by wind
k1,K2 factors,structure types
Check the terrain category->In this case it is category 2
Fetch distance is the clear distance between other buildings from your building.
Click Next->then comes topography(if you want any,then select )or click NExt
Now the resultant wind pressure is shown which are acting on the structure.
Now click on finish.
Now on wind load tab->Click on wind loadcases
enter the loadcases you want manually
Now the loads were applied on the structure in all the direction as per the values entered
Click on validation to check for any errors->No errors are shown
