Hybrid Simulation with Improved Operator-Splitting Integration Using Experimental Tangent Stiffness Matrix Estimation
Publisher: American Society of Civil Engineers
Abstract: Improved numerical integration procedures are essential for the extension of hybrid numerical and experimental simulation to large and complex structural systems. While implicit integration algorithms are widely used in ...
Simplified Nonlinear Model of Straight-Sheathed Wood Diaphragms in Unreinforced Masonry Buildings
Publisher: ASCE
Abstract: A simplified nonlinear numerical model is proposed to predict the full dynamic response of straight-sheathed wood diaphragms in unreinforced masonry buildings. The straight-sheathing system is replaced with an equivalent ...
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 ...
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. ...
