FW: Slender Masonry Walls, Again

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Take a look at UBC 1612.2.1 exception 2.  This passage requires that the
ASCE (LRFD) load factors be multiplied by 1.1 for concrete and masonry for
load combinations including seismic.  That should get you close to the
original ACI load factors.

Not to sound like a sheep, but I am reluctant to diverge from the load
factors per code, since I know that in many instances much research went
into calibrating them.
