Performance-Based Seismic Design of Shape Memory Alloy–Reinforced Concrete Bridge Piers. II: Methodology and Design Example

Abstract

Here, a performance-based seismic design method is presented for shape memory alloy (SMA)-reinforced concrete (RC) bridge piers. The proposed design method is developed based on the existing displacement-based procedure where the expected performance is quantified by linking material strains and deformations to damage states, as well as to the probable postearthquake functionality of a bridge. Based on the performance-based damage states developed in a companion paper, this study presents the sequential procedure for the performance-based design of SMA-RC bridge piers using a combination of residual and maximum drift.
