Re: Question for East Coast Engineers

[Subject Prev][Subject Next][Thread Prev][Thread Next]
It has been my experience (though somewhat limited) that wind loads only
become a REAL problem in coastal areas here in the east.  While most of my
wood design experience is with residential structures in SBC 80 mph wind
zones, I have had the opportunity to work on some 4 and 5 story hotels and
apartment buildings in central and southern Florida.  In these situations,
lateral design is a VERY important consideration, requiring more than just a
cursory analysis.  For the balance of projects, however, Simpson H2.5's at
ea. roof truss and plywood shear walls w/ minimum nailing will almost always
be adequate.
