Does anybody knows something about the Earthquake mode option included in the RC Designer in STAAD 2006 (specially ACI check)? I asked REI, but they don't answer me yet?
I´m using Staad 2003, in the concrete design the software crashs trying to design beams.
I made a hand-check and the moments and shears are in the normal range for the beam´s section, so there should be no problem.
There is a solution for that?
Regards
I would like to compare UBC 97 and ACI-530 about boundary element requirement for masonry shear wall. I know that UBC require boundary element when compressive strain is greater than 0.0015 using factored load and R=1.1. I don't have ACI-530 can somebody explains me the ACI-530 criteria?
Thanks
I would like to get a freeware to design masonry shear wall using ACI-530 or UBC 97 also I'd like to find the procedure to do this (by hand). Anybody knows where can I get it?
Please help
