Wind load on open box

[Subject Prev][Subject Next][Thread Prev][Thread Next] Have an existing 20'x20'x16'height box with the top open. The box sets on the top of a roof.

Question: Does the second (leeward wall) pick up full wind pressure as the first wall? Any good references for how much the second wall will pick up.

In the past I have always been conservative and used full pressures on both. What if the bax were smaller the first wall would shield the second wall and you would think pressures would be less.

Any comments
