Exterior Climbing Walls - Wind Load
Exterior Climbing Walls - Wind Load
(OP)
I'm analyzing the effects of attaching two climbing walls to the sides of an existing old open framed radar tower. The climbing walls will be attached to two adjacent sides of the tower. The tower is square, 24 feet along each side and 26 feet high.
My concern is the wind pressure that will develop on the inside corner as the wind blows through the tower frame. ASCE 7 doesn't really address inside corners very well. The load diagram in Figure 6-9, Case 3, indicates a reduced pressure value for wind attacking a building at an angle to an outside corner. This makes sense since the air will flow aerodynamically from the corner as opposed to creating a stagnation pressure as it would if it was blowing normal to the wall. However, I'm thinking the pressure on an inside corner would be the full force of Pwx and Pwy applied simultaneously. Does this make sense?

But also make sure you check for wind at 45 degrees hitting both walls?? That may be the worst condition.

If there is a significant gap between the two signs then there will be a greater wind at 45 degrees than flat on.

You are wrong with that assmption, just because it forms a scoop does not necesarily mean that it is the highest wind pressure.
For hoardings and walls the highest pressure is when the wind blows at 45 degrees to the end as this creates fluctuating wind gusts.
