1/3 increase for seismic/wind for masonry?
(OP)
There has been some talk that the 1/3 increase for masonry is going away in the IBC 2006. But it's still in the IBC 2003, right? 2.1.2.3 of the ACI 530-02/ASCE 5-02 seems to allow the 1/3 stress increase, which can be used with the ALTERNATIVE basic load combinations of the IBC 2003.
What do you think?
