Building dimensions to consider when finding wind loads?
Building dimensions to consider when finding wind loads?
(OP)
Hello all,
Please see attached screenshot for a description of the building. Note: Building is adjacent to a retaining wall in one direction only. The direction perpendicular to the screenshot is open to the elements. I am curious as to which building dimensions I should consider when finding wind loads? What is usually the approach when one has a building like this? Thanks.

Have you checked this area under seismic loads.
I would never desgign the shielded area for zero wind pressure, there will be some wind loads exerted by gusts..
RE: Building dimensions to consider when finding wind loads?
I have yet to run a seismic analysis.
I am planning on obtaining wind loads by using the maximum height and width of the building, fairly conservative, but practical. Do you think this is a reasonable thing to do?
RE: Building dimensions to consider when finding wind loads?
I think all that you are saying is justifyable under code but personally I would err a little on the conservative side.

When finding net line loads on the roof purlin of a "high rise building", it seems like the Canadian code does not have any internal suction/pressure for the roof, except suction for the edge and corners. The suction on the edge/corners counteract the snow load when putting these forces into a combination, which got me thinking...is this the way it should be? Also, why would a high rise building (H>120m, H/w>4) not have any internal suction or internal pressure? Thanks!
RE: Building dimensions to consider when finding wind loads?
1. When finding load applied on roof to find the required cladding capacity, the suction on the roof when placed counteracts when placed in a combination with snow load. Am I understanding something wrong here?
2. Should I use specified loads when determining loads on cladding? Also, should I be using the 1-10 year wind or the 1-50 year?
Thanks.

Consider partial snow loading in a place that adds to the wind effect(possibly the leeward side).
