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