Re: When wind governs with No Seismic

IBC Section 1604.10, detailing requirements for the LFRS is per ASCE 7, regardless of wind or seismic forces governing.

Subject When wind governs with No Seismic

I am working on a big project where lateral (hurricane level) wind loads are more than 0.1W.  The structure has many irregularities such as non-parallel systems, discontinuous lateral systems, more than 40% area openings in floor diaphragms, curved and barrel roofs, etc.
The project is in Bahamas where local codes follow the Florida IBC and do NOT require/consider seismic loads.

What are the basis for design of lateral load elements such disphragms, collectors, discontinuous columns, OMF and OCBF connections???  The UBC-IBC methodology is to provide the minimum seismic requirements even though wind loads govern over seismic.  How do you interprate this when there is NO seismic ???
