Wind load Analysis on a Circular Building with a Dome Roof

[PurdueEng]

If there is anyone out there that could give me some tips on how to analyze a circluar building with a dome roof that would be great. The roof's mean height is greater than 60' so I cannot use method 1 of the ASCE 7-98. I figured I would have to use method 2. Under method 2 the Cp value is confusing me, what table in ASCE 7-98 should this be taken from? The building's mean roof height is 76.5' and the diameter is 152'. The building is Mackey Basketball Arena at Purdue University. Thanks for any help you can give.

The question is not (I think) where to find the loads for this kind of building; for example, spanish code on loads NBE AE-88 would give clear indication of the loads for such a building. The question is if you must stay within some specific code, and hence from only the same derive the loads, for which case other may be of more help than me.

Anyway, the book

Steel, Concrete & Composite Design of Tall Buildings,
2nd. ed.
Bungale S. Taranath
Mc Graw Hill

was quite good at explaining ASCE's wind loads (yet this 2nd. edition wouldn't be yet the last ASCE's).

PurdueEng,

Figure 6-16 of ASCE 7-02 gives the GCp coefficients for Domed Roofs for all heights of buidings.
