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

1.To generate manual wind loading in the design report based on IS code for the given inputs, you can follow these steps:

1. Determine the importance factor: The importance factor for the structure needs to be determined based on its intended use. For the purpose of this calculation, let's assume an importance factor of 1.0.

2. Determine the terrain roughness factor: The terrain roughness factor depends on the surrounding terrain and the height of the structure. For terrain category 2, the terrain roughness factor is 0.18.

3. Determine the design wind speed: The design wind speed can be calculated using the following formula:

Design wind speed = Basic wind speed x Importance factor x Terrain roughness factor = 39 m/s x 1.0 x 0.18 = 7.02 m/s

4. Determine the wind pressure: The wind pressure can be calculated using the following formula:

Wind pressure = 0.6 x Design wind speed^2 = 0.6 x (7.02 m/s)^2 = 29.66 N/m2

5. Determine the external pressure coefficient: The external pressure coefficient depends on the shape and orientation of the structure. For a flat roof, the external pressure coefficient is -0.7.

6. Determine the internal pressure coefficient: The internal pressure coefficient depends on the ventilation and openings in the structure. For a closed building with no ventilation or openings, the internal pressure coefficient is 0.0.

7. Determine the net pressure: The net pressure is the difference between the external and internal pressures. For a flat roof with no ventilation or openings, the net pressure would be:

Net pressure = Wind pressure x External pressure coefficient = 29.66 N/m2 x -0.7 = -20.76 N/m2

8. Apply the wind loading on the structure: The wind loading can be applied on the structure by assigning the calculated net pressure values to the appropriate surfaces of the 3D model of the structure.

To generate manual wind loading in the design report based on the Indian Standard (IS) code, we would need additional information such as the height of the building, its shape, and the type of construction. However, I can provide some general guidance on how to apply wind loads based on the inputs you have provided.

As per the IS code, the wind load is calculated as follows:

Wind Pressure (P) = KZ × Kzt × Kd × V^2

where:

• KZ is the velocity pressure coefficient
• Kzt is the topographic factor
• Kd is the wind directionality factor
• V is the basic wind speed

For terrain category 2, the value of KZ can be taken as 0.30. The topographic factor depends on the site location and should be determined from the code. The wind directionality factor is taken as 1.0 for buildings with a height of up to 60m.

Once the wind pressure is calculated, it can be applied to the building as a uniformly distributed load. The load should be distributed over the appropriate area of the building based on its shape and orientation.

As for generating wind loading using Wind Wizard, it is a software tool that can simulate wind loads on a virtual model of the building. To use Wind Wizard, you would need to provide information about the building, such as its height, shape, and location. The software will then use computational fluid dynamics (CFD) to simulate the wind flow around the building and generate wind pressure data that can be applied to the model. The output can be in the form of pressure coefficients or loads that can be used for design purposes.
