RE: Question for East Coast Engineers

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Unless I am wrong, this is not the case with the UBC. I know of no
prescriptive measure in the jurisdiction of the UBC that provides a table
for the selection of headers.
Any takers on this topic in other area's of the country? Who determines
appropriate header design? If a beam exists in a conventional framed
building, is this covered under a prescriptive table or is it necessary to
hire an engineer or architect to design only this portion of the structure?

The 'prescriptive' method here is the "Guide to Wood Construction in High
Winds Areas", or the SSTD-10.  The first is a publication of the Wood
Products Promotion Council, the second is a publication of the Southern
Standard Building Code Congress International (SBCCI)  - the Code in Florida
(other than Dade & Broward Counties).

It's been a while since I used the SSTD-10, but the "guide" is newer and is
being promoted by the State and local building departments.  It has tables
for headers, jambs, shear panels, hold-downs, etc. etc.  for the 100 & 110
MPH wind speeds.
