Wind Loads for a portal frame
Wind Loads for a portal frame
(OP)
We are having a debate in our office. Historically, we only use Horizontal wind Pressures found in figure 6-2 of ASCE-07-05 to determine the lateral load for the design of a portal frame. A new Engineer here believes we have to use the vertical pressures also and apply them to the frame. Does anyone know of a reference that would clarify this for us?






RE: Wind Loads for a portal frame
Secondly, to do so, you also have to account for roof pressure that affect moment in columns !
Check figure 27.4.1 P263 of ACe 7-10, it pretty confirm what to apply for gable hip roof portal.
