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

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

Introduction:

• Lateral Load Calculation and Application
• Validation of model after the loading Application
• Here first we will calculate the wind load manually
• And create the model to apply the load
• In the TEKLA Structural Designer we have a Option of calculating the wind load inside the software using the REC WiIZARD
• But here generaly our live projects we calculate the wind loand manualy and then applied on the Software

To creat the Wind and roof panel

• Open TEKLA Structureal Designed to software form my disktop
• Go to file menu to open the previous Challenge-4 Poject
• Now we wil Creat the Wind shield and Roof Sheild by using Wall and roof panel
• Go to Model , Under the model tab ther is option called Wall panel
• Selct Wall panel, then Pick the Point 1, Point 1, Point 2, Point 3, Point 4 Escape
• Similarly all the wind sheild are created

Aim: To Generate manual wind loading in the design report based IS code as per the following input

• Basic wind speed = 39m/s
• Terrain category 2

Procedure:

• Now To Calculate the wind load As per IS: 875 P3-2005
• Open the Excel Document File For Calculating the Wind load Calculation
• Initialy we wil Give the Basic Parmeters value of :
  1. Basic Wind speed Vb
  2. Probable design life of structure
  3. Terrain category
  4. Ratio for wall & roof co-efficient value
  5. Topography factor and etc...
• The Follwoing Calculation Are calculated by using IS: 875 P3-2005 Excel Document Fil

I. Wind Load Calculation:

II. Tekla Co-ordinates and External Wall Roof Co-eficient :

III. Roof Co-eficient :

IV. Wall Loading Calculation : Y direction

Similarly All wind load area calculated in the X-direction as the same procedure follwoed above

V. Roof Loading Calculation :

Wind load along Y- dorection (Roof EF and GH)

Vi. Roof Loading Calculation :

Wind load along X- dorection (Roof EG and FH)

Result: The Wind load Manual calculation are calculated used Above the procedure by uisng Excel Docement File

Aim: To Based on the above calculation apply the loadings on the model

Procedure:

Step-1

• Now After Calculated of Wind load calculation To be apply the loading on the Model
• Take Previous Challenge File in TEKLA Software
• Now we have to creat the Loadcase
• Select Loadcase Option are located in under the Load Tab
• Add add the Loadcases
• Type Wind +Y +Cpi
• Types of Load case as Wind
• Again Type Wind +Y -Cpi
• Types of Load case as Wind
• Again Type Wind +X +Cpi
• Types of Load case as Wind
• Again Type Wind +X -Cpi
• Types of Load case as Wind
• Similarly all the Load case are created as given below :

• Press Ok
• Now we have to start applyin the Load case

Step-2

• First we will to select the wind loasd case from bottom
• Then We will Input the value to apply the loadcase On Different Face
• The +X direction Grid G is: Face-A
• The Grid C is: Face-B
• The +Y Grid 1 is: Face-C
• The Grid C is: Face-D
• Next to go to Excel File
• And then chek the wind load value to apply on the model
