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: Given: Basic wind speed = 39m/s Terrain category 2 Based on the above calculations Vb 39 m/s terrain category 2 probable design life of structure 50 years class of structure

Result: Generation of manual wind loading in the design report based IS code as per the following input was done
Aim: in model generate wind loading using wind wizard 6/9 Procedure: In load ta click on the wind wizard option Add wind speed 39 Terri category 2 Fetch distance 10m Topography none next and finish Define wind loadcases And check all the panels are I the same direction More projects by Srinivasa Result: model is generated for wind loading using wind wizard
