TI-809-04

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Harold,
On two projects I have compared base shear calculated per TI-809-04/FEMA
302, to that calculated per UBC 97.  Both projects were in Southern CA,
seismic use group 1.  In these two instances the base shear calculated per
UBC 97 zone 4 was higher than the TI-809-04/FEMA 302 base shear, so we used
the higher base shear.  If we'd considered either seismic use group 2 or 3
the calculated base shear probably would have exceeded the UBC 97 calculated
base shear.

Subject: USACE TI 809-04 Seismic Design for Buildings

I am using the USACE TI 809-04 "Seismic Design for Buildings" dated 31
December 1998 for the first time.  I would appreciate any reviews, comments,
or sage words of advice as I wander through this new forest of Corps code.
If you don't have it you should get it.  

Regards,
Harold Sprague
