Abstract: Concrete-filled steel tubes (CFTs) have recently been used for columns and bridge piers, especially in seismic regions, for their enhanced strength and ductility over the conventional steel and concrete construction. This ...

Abstract: The heated deck of Roca Spur Bridge is the first implementation in the world using conductive concrete for deicing. Conductive concrete is a concrete mix containing a certain amount of electrically conductive components ...

Abstract: A viscoplastic cap model of the Perzyna type was developed for simulating high strain rate behaviors of soils. An associative viscous flow rule was used to represent time-dependent soil behaviors. The viscoplastic cap model ...

Abstract: Typical spectator movements were simulated by persons individually on a force platform with which dynamic force components were measured. Impulsive loadings are produced by movements such as rising, sitting, or jumping off ...

Abstract: Present U.S. structural engineering practice assumes that live load components due to human occupancy and human movements for the design of assembly structures, such as grandstands, can be represented as statically applied ...

Abstract: High‐quality optical reflector surfaces are attainable with the use of pressure‐formed membranes. The formation technique involves gradual application of fluid pressure on initially flat, simply supported circular membranes ...

Abstract: High‐quality optical reflector surfaces are attainable with the i use of pressure‐formed membranes. Those reflector surfaces offer the prospect of very light weight and low cost. The formation of those surfaces, using ...

Abstract: Fatigue cracks were found on a series of end-coped crane runway girders after 14 years of service in a steel mill building in China. Two typical crane runway girders with different spans were studied in this paper. Finite ...
