PBEE Assessment and Design of Enhanced Bridge Piers for Near Field Effects The overall goal of this study is to examine and assess various design concepts for enhancing the seismic performance of new bridge structures of the type being considered by PEER. Promising design details will be assessed though dynamic shaking table and/or quasi-static tests as well as through more extensive nonlinear dynamic analyses using the OpenSees computational framework. In particular, the potential for reducing residual displacements of bridges following severe earthquakes will be examined through the use of special plastic hinge regions containing combinations of unbonded prestressed and mild reinforcement. Other design approaches utilizing high performance concrete will be examined in concert with others working within the PEER Center. The results will be presented in a fashion that will support the development and assessment of the overall PEER PBEE methodology being devised by the Bridge and Transportation Thrust Area. The goal of this project would be to demonstrate physically and through PBEE the value of the PEER methodology for a specific application, and thereby accelerate the adoption of new bridge design technologies into practice.
