It is a matter of concern that, in staad pro, the features available for applying wind load is not fully automatic (unlike other design softwares) , but there is much more lacking in it, which is briefly described as below, There is automatic application of wind load only for few types/shapes of roofs/structures ,like rectangular building,pitched roof, mono slope roofs. For many other types of roofs, like saw toothed roof,cantilever roof,multispan pitched roof, combined roof, inverted pitched roof, inverted mono slope roofs, cylindrical shaped structures etc, the automation of wind load is not available, (or available partly). Moreover, automatic wind load for all types and shapes of "ROOF PURLINS", "COMMUNICATION TOWERS", wind load on circular or elliptical shaped column is not available in staad, local wind coefficient (for corner pressures) is not available, automatic calculated solidity ratio/ shielding factor is not available. It is very demanding that wind load in staad should be available for all types of roofs and purlins with Full automation and can be applied with few clicks, For illustration, refer "TABLE NO. 04 to 24" of IS 875 part -3", refer following PDFs 1st PDFs: wind load on frames 2 nd PDFs: wind load on roof purlins. In short, wind load in staad should be available for all types/shapes of of roof/building, purlins and not only for global X and Z directions ,but it should also available for 45⁰,135⁰,225⁰,315⁰,270⁰ etc.

Thank you for posting your idea. It is best to post each idea separately so you can be notified as each gets addressed. With regard to each, can you expand on 'how' the program might operate. What rules would it use and how would you expect to apply them? The connection design idea seems like a feature you would apply in the Connection Design module I.e. RAM Connection) and then that would be consumed in the Steel Connection Design module in STAAD.Pro. With the Roof loading, Are you looking for essentially the load vector to be perpendicular to the roof surface as opposed to parallel to the wind direction as we currently offer?
