A hybrid simulation approach is proposed to conduct the nonlinear seismic analysis of the bridge/traffic/earthquake system by integrating the stochastic traffic flow simulation, the mode-based fully-coupled simulation technique of the bridge-traffic system, and the nonlinear seismic analysis platform that was developed based on OpenSees.Posted: Sep 18 Catherine Tucker and Luis Ibarra
This study evaluates the seismic performance of circular concrete-filled tube (CCFT) columns in accelerated bridge construction (ABC) projects.Posted: Sep 17 Suren Chen and Yufen Zhou
To study the seismic performance of bridge and traffic systems, a new full-response prediction methodology for the coupled bridge-traffic interaction system under spatially varying earthquake excitations was developed by capturing the interaction effects not only between the bridge and moving vehicles, but also between earthquake excitations and the coupled bridge-traffic system.Posted: Sep 12 The proposed project will seek to develop a training model and implementation plan and materials that can serve as a blueprint and road map for training leaders in transit and freight organizations to systematically promote and develop an effective safety culture.
