Frequently used for design of all steel structure with shed/roof

CONCERN CODE(ALL) especially IS 875 part 3: 1-Sir, staad CE has support the auto wind load as for clad/unclad buildings, this wind load is applied on the surfaces/periphery of buildings or the same is applied on the exposed members of structure, but as far as the wind load for roof/purlin is considered,there isnt automated option for purlin/roof wind load, we hve put much more manual efforts for applying wind load on roof/purlin as per conditions of roof,like for curved roof, monoslope roof, pitched roof, combined roof,toothed roof etc, for each roof we have to calculate wind load and its coefficient manually, and the same is applied on roof purlins, in addition to this, for some roof, there are trial and error process for applying wind load, like calculate the solidity ratio from exposed member width and depth and then apply wind load on roof purlins. If the member is failed in strengh/serviceability criteria, we have to revise the member and have to repeat the same procedure again for calulating the solidity ratio and apply wind load again, this is much more tedious abd time consuming process, kindly automate this feature in staad for all types and shapes of roof/roof purlins...... Also for the roof/purlins that is in uneven shape.. 2. Also automate the feature of dynamic wind load such as gust factor etc particularly for indian code...
