RE: Skin friction from wind load for buildings

[Subject Prev][Subject Next][Thread Prev][Thread Next]

The only thing that I'm aware of is the provisions for tanks and roughness
as in ASCE 7-98 Table 6-10.  One thing of note is that the Cf  and the
resulting pressure is a function of both roughness and the tank aspect

Anything else would probably require testing.  If you have something
specific in mind, I would suggest you talk to the people at CPP, RWDI, or you could post your
question on the web site.
