How can you place surface wind loads, when you have a custom shaped flat roof, instead of the standard types, what you can see in Eurocode?
Step 1 -Calculate wind load intensities
With ConSteel, one possible solution is to cover the roof with a load transfer surface, which fits to the edge of the building from the wind direction, and run the wind load generation. As a result, you get the zones (F,G,H,I) with proper dimensions, and with proper wind load intensities.
Step 2 -place the loads for each zones
After this, you should create a new load transfer surface, which now, fits to the edges of the building (with draw polygon option). Next, is to place the previously calculated load intensities for each zones with using the "create surface load option". With this option, you are able to place more different surface loads inside of a load transfer surface.
