Wind Load of Ridge Skylight or Hip Skylight at a Flat Roof?

Hi everyone,

How to calculate positive and negative wind loads of a ridge skylight or hip skylight located at a flat roof of a building?

Any comment appreciated.

RE: Wind Load of Ridge Skylight or Hip Skylight at a Flat Roof?

This is wholly dependant on your Code.  What are you using?

If this is new construction, contact the supplier.  They will give you some preliminary design loads (that I usually increase some percentage) to work with.

Use the components and cladding portion of the wind provisions of the bldg code for a roof component.

Reply all above:

To youngstrucutal: The load code is ASCE 7.

To SperlingPE: Why do you think we need contact the supplier? We are structural engineers. I think we need to find it out by ourselves using wind speed and building dimesions, etc.

To SteveGregory: what's code you refer? where are roof components? I can't find any roof component in Components and Cladding, ASCE 7.

Thanks for you guys' inputs.

RE: Wind Load of Ridge Skylight or Hip Skylight at a Flat Roof?

I am refering to ASCE 7-02. Section 6.5.12.4 refers to components and cladding. See figures 6-11 through 6-17 for the GCp pressure coefficients for a variety of roof components.  Other editions of ASCE 7 have similar figures.
