Benchmarking Enhanced Performance of Post-Tensioned RC Piers with Ductile Materials The overall goal of this study is to demonstrate how the PEER PBEE methodology can accelerate the adoption of new bridge design technologies by quantitatively assessing the performance enhancement provided by these technologies. We will be demonstrating the application of the PBEE methodology while also identifying where in the process the uncertainties have the most impact on the final assessment. The demonstration will be performed on a baseline bridge also studied by other researchers in PEERs Thrust 2 area, to facilitate comparisons of performance assessment. The technologies investigated here apply to the design of bridge piers and will focus on unbonded vertical post-tensioning for self-centering, segmentally precast concrete, and high performance fiber-reinforced concrete materials for localized regions of a structure. IM-EDP and EDP-DM relationships will be developed analytically using a combination of OpenSees modeling and where necessary, more advanced finite element (continuum) modeling. All models have been or are being calibrated again recent cyclic and seismic experiments on reinforced concrete and enhanced-performance bridge piers.
