Carport Wind Load

Carport Wind Load

Carport Wind Load

(OP)
What is the wind uplift load on a free standing or attached one side only ( to a house) lightweight alumunum carport sturcture.
ASCE-7 shows uplift for enclosed and partially enclosed structures but implies there is only horizontal wind load on open (all sides) structure. Am I missing something?

RE: Carport Wind Load

You aren't missing something, ASCE 7 is.  Your options are to make an educated guess with your engineering judgment and the information you do have or find another code that addresses the problem.

RE: Carport Wind Load

The Australian Wind Code AS/NZS 1170.2 does cover this situation. Coefficients vary from +1.2 to - 1.5, depending on relative heights (canopy to bldg) and canopy width.

RE: Carport Wind Load

SacreBleu, thank you for listing thread507-75003.  The problem I run into,is that the copy of ASCE-7 which I currently have,doesn't included coefficients for open structures with gable or hip roof systems. In case like that I usually use an old copy of the UBC.  Fortunately for the open structures I design the magnitude of wind uplift doesn't impact the design very much.
