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!
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!
