Wind Load - Gas Station Overhead

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Title: Wind Load - Gas Station Overhead

Gas pump island canopies would, I think, be considered a free roof on an open building. Wind coefficients for free roofs are provided in ASCE 7-05 in Figures 6-18 and 6-19. The loads are not uniform, and will result in a moment being applied to the support framing. You might want to add something for the side load on the edges if the sides present much of a profile to the wind.
