Design Wind Loads on Open Structures
Design Wind Loads on Open Structures
(OP)
Would anyone know where I can find an article or information on wind load magnitudes on open structures. BOCA and ASCE-7 give guidance for roof overhangs and open structures with roof slopes however they do not specifically address other open structures.
I am currently working on a small project where the budget does not allow for a wind tunnel study. The stucture is located at the shore.

Good luck.

A very good source of information is the ASCE Publication "Wind Loads and Anchor Bolt Design for Petrochemical Facilities". It has good discussions and design examples for Open Framed Structures.

P.S. I am a structural engineer. If STLBlueRam sees this, I'd appreciate a response.

I stand corrected, equation 6-20 is the more relevant equation in this case. I should have gone to the code instead of citing references contained in my spreadsheet.
By the way, CAB30 refers to his/her's structure as an "other open structure", not an "open building", as a result I would assume that what he/she is talking about is a structure w/o a roof. If CAB30's structure is w/o a roof, it is acceptable practice to treat this structure as a trussed tower and ASCE-7 98 gives a method to determine design wind pressure on such a structure.
P.S.: I prefer to use eqn. 6-15 w/ Cf defined per Table 6-13, qz defined per Section 6.5.13, and GCpi defined per Table 6.7.... just personal preference. Have a nice day.
