Abstract: Some proof that politics and culture bear direct influence on innovation in bridge design comes from post-World War II Germany, which has promoted structural innovations through bridge design competitions. The design ...

Abstract: Current US seismic design provisions allow structures in areas of lower seismicity (e.g., the Midwest and eastern North America) to be designed with modest seismic requirements as compared with the requirements that ...

Abstract: Partially restrained beam-column connections such as bolted double web with top and seat angle connections can be used in the gravity load system of steel buildings to develop secondary moment frame action and enhance ...

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: Double-web-angle beam–column connections are used extensively for gravity framing in steel buildings. Although they are designed to resist shear and to allow rotation, they still possess moment capacity that may contribute ...

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 ...
