What "R" value (overstrength/ductility coefficient) per '97 UBC would I use for the seismic design of a steel framed building (typ 1 story metal bldg)in the opposite direction of the moment frames, where tension only bracing is used to resist lateral forces. Thanks!
My office uses RetainPro. It does cantilever & restrained walls with concrete & masonry. It is pretty user friendly and includes seismic loading as an option. We just got version 6, but the prior version would freeze up quite a bit, especially if you made a lot of changes. I think the same...
Dave,
Do I consider the length for the PL/AE calc to be the total strap length? My strap will be attached to each stud in the wall system as it crosses the studs(16"o.c.), will this possibly reduce the effective length for elongation? It seems to me that the presence of the studs would add...
I am using tension only bracing to resist lateral forces for a mezzanine framed with light gage steel studs. What is the best way to hand calc the rigidity of the braced wall, to distribute lateral forces to walls of different lengths. Thanks!
