Hybrid Simulation of Bridge Response to Three-Dimensional Earthquake Excitation Followed by Truck Load
Publisher: American Society of Civil Engineers
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 ...
Probabilistic Seismic Demand Model for California Highway Bridges
Publisher: American Society of Civil Engineers
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 ...
Cyclic Tests Performed on Real-Scale Squat Reinforced Concrete Shear Walls: Transition between Diagonal Shear and Sliding Shear Controlled Behavior Modes
Publisher: American Society of Civil Engineers
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 ...
Effect of Ground Motion Sequence on Response of Squat Reinforced Concrete Shear Walls
Publisher: American Society of Civil Engineers
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 ...
R -Factor Parameterized Bridge Damage Fragility Curves
Publisher: American Society of Civil Engineers
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 ...
Event-Driven Control System for Geographically Distributed Hybrid Simulation
Publisher: American Society of Civil Engineers
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 ...
Energy-based Seismic Design of Structures using Yield Mechanism and Target Drift
Publisher: American Society of Civil Engineers
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 ...
Seismic Performance of Pre-Northridge Welded Steel Moment Connections to Built-Up Box Columns
Publisher: American Society of Civil Engineers
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 ...
Real-Time Error Monitoring for Hybrid Simulation. Part II: Structural Response Modification due to Errors
Publisher: American Society of Civil Engineers
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 ...
Real-Time Error Monitoring for Hybrid Simulation. Part I: Methodology and Experimental Verification
Publisher: American Society of Civil Engineers
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. ...
