ABSTRACT

Steel-framed industrial buildings generally per formed well in recent earthquakes with most of the structural damage that has been reported being limited to individual components or connections, not to structural collapse. For instance, the damage observed after the 1999 Kocaeli, Turkey, earthquake included bolt shearing at column to roof truss connections in automotive plants, buckled and fractured braces, stretching and fracture of anchor bolts in moment-resist ing frames, and shearing of anchor bolts (Bendimerad et al. 1999; Rahnama & Morrow 2000; Sezen et al. 2000; Johnson et al. 2000). The 1994 Northridge earthquake caused yielding and failure of anchor bolts in an asphalt rock plant and brace buckling in a brewing facility (Tremblay et al. 1995). Failure of welds at brace connections was ob served after the 1988 Spitak, Armenia, earthquake (Yanev 1989).
