Design Wind Load Cases for Components and Cladding

[Erudawn]

Figure 27.3-8 of ASCE SEI 7-16 (p. 283) shows design wind load cases for Main Wind Force Resisting System of a building for all heights.
I was wondering if this load case is also applicable in designing components and cladding?

I am having a hard time figuring out the load cases I needed to consider for the aluminum corner mullion.
At the moment, I am considering a load case wherein one side is experiencing full positive design wind pressure
and a concurrent full negative design wind pressure on the other side.

Case 3 of Figure 27.3-8, however, shows that 75% of the load should only be considered when loads are acting simultaneously.

Hi Erudawn,

Figure 28.3-8 are load cases intended for overall structural wind loading, not for designing components and cladding.

What kind of element are you considering? Is it glazing?
For glazing on an enclosed building, you only normally need to consider two cases:
1). Cpe,+ve - Cpi,-ve (external positive - internal negative)
2). Cpe,-ve - Cpi,+ve (external negative - internal positive)

Hope that helps.
Let me know if you have any questions.
