Abstract: A hybrid simulation approach is used to evaluate the traffic performance of a typical California highway overpass bridge after a major earthquake. The prototype bridge used in this study is a five-span single-column-bent ...

Abstract: The objective evaluation of the capacity of a bridge to carry self-weight and traffic loads after an earthquake is essential for a safe and timely reopening of the bridge; this performance goal gains in importance with the ...

Abstract: A performance-based seismic design method enables designers to evaluate a graduated suite of performance levels for a structure in a given hazard environment. The Pacific Earthquake Engineering Research Center is developing ...

Abstract: Squat reinforced concrete shear walls are commonly used as primary gravity and lateral load–resisting systems in structures. Such low aspect ratio walls respond to load in diagonal or sliding shear. A series of real-scale ...

Abstract: An algorithm has been developed for the stable analysis of reinforced‐concrete cross sections of arbitrary shape. The algorithm is based on a modified event‐to‐event scheme and is free of the convergence problems that have ...

Abstract: Fourway is a simple graphical tool for estimating the conditional dependence of decision variables involved in the seismic design process on the earthquake intensity. The tool was formulated for use with the Pacific ...

Abstract: Most industrial and nuclear facilities rely on reinforced concrete structural walls as their primary seismic lateral-force-resisting components. In nuclear facility structures, squat walls commonly have an aspect ratio ...

Abstract: Damage fragilities describe the probability that a bridge will incur certain (discrete) damage states conditioned on the intensity of the earthquake it may experience. Reinforced concrete box girder highway overpass bridges ...

Abstract: An event-driven distributed control system for conducting continuous seismic response simulations using geographically distributed hybrid models is presented. Hybrid models, comprising appropriately scaled experimental and ...

Abstract: The use of energy as means to derive seismic design forces is discussed in this paper. The energy balance concept used in deriving seismic design forces for single-degree-of-freedom systems is extended and used to derive ...
