The impact of a PEER funded research project “Accounting for Earthquake Duration in Performance- Based Evaluation and Design of Bridges (UNR-Stanford Collaboration)” is highlighted below. The project Principal Investigator is David H. Sanders, University of Nevada, Reno. The research team includes John Anderson, University of Nevada, Reno; Greg Deierlein, Stanford University; and Mohammed Saeed Mohammed, Dynamic Isolation Services.
This project will develop seismic design provisions that account for earthquake duration effects, which are especially for Northern California, Oregon, and Washington where large subduction earthquakes are expected to occur. The project will also contribute to the reliable use of high-strength reinforcement for bridges in high seismic regions and develop details for mitigating duration impact. The PI’s will work with Caltrans, AASHTO, ACI, and other organizations to implement the research findings into design standards.
