RE: Question for East Coast Engineers

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Lew, where is the prescriptive method for the design of headers? Someone
threw this at me a few weeks ago and I never even considered that most
contractors are building headers by rule of thumb. Does this suddenly put
any structure into a non-compliance with conventional framing? Section
2326.11.6 of the '94 UBC only specifies the width of headers and the minimum
amount of bearing at the ends. It does not state where the prescriptive
measure for the depth of the headers can be found.
Any comments?

This is exactly what is now being done throughout Florida.  A contractor can
apply for a permit, without engineering (for residences), using the code's
'prescriptive' design, but they have to identify hold-downs, anchors,
sheathing, door & window jambs & anchors, anchors, etc, etc. ; and submit
pre-fab assemblies (such as roof trusses) fully designed, and with an
engineer's seal.  And if anything is out of the norm (today's norm, not the
way they've "always done it") then engineering is required.  Most, if not
all, of the building departments are enforcing this approach.

As I said in a previous post, Florida has learned its lesson.  Seismic
zone=0,  Wind zone='way up there'.
