![]() ![]() Wind pressure at each zone needs to be calculated separately. If site conditions and locations of structures do not meet all the conditions specified in section 26.8.1 then K zt 1.0.įor partially enclosed building, internal pressure shall be added to the leeward wall at the height of the opening. The velocity pressure is depending on wind speed and topographic location of a structure as per the code standard velocity pressure, q z equivalent at height z shall be calculated as. ![]() Regardless of which analysis approaches we may use, velocity pressure is a requirement. You are going to need a copy of the ASCE 7-10 code for sections, figures and table references. The simplified procedure is for building with a simple diaphragm, roof slope less than 10 degrees, mean roof height less than 30 feet (9 meters), regular shape rigid building, no expansion joints, flat terrain and not subjected to special wind condition.Įach procedure has two categories: wind for the main wind force-resisting system (MWFRS) and wind for component and claddings (CC). Nevertheless, the code set a standard in determining wind procedure that we require in our design. ![]()
