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: 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: 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 ...

Abstract: Results of experimental and analytical investigations of the seismic response of fully restrained steel moment connections between deep W-shape beams and deep and square built-up box columns are presented. Prototype ...

Abstract: Hybrid simulation results have been shown to be highly sensitive to measurement and control errors associated with experimental substructures. In particular, systematic control errors due to the response lag of servohydraulic ...

Abstract: The hybrid simulation test method is a versatile technique for evaluating the seismic performance of structures by seamlessly integrating both physical and numerical simulations of substructures into a single test model. ...
