Abstract: In moderate-seismic regions, cost-effective steel building design solutions such as the R=3 and ordinary concentrically braced frame (OCBF) systems do not consistently provide reliable life-safety protection. The collapse ...

Abstract: This article describes an extensive experimental program that was conducted to characterize comprehensively the nonlinear sectional force-displacement response of bolted steel angle semirigid connections. A total of 139 ...
