Abstract

In this study, the seismic performance of self-centring precast segmental bridge columns with shape memory alloy (SMA) bars are analytically investigated. Nonlinear finite element analyses are conducted. This is shown that the self-centring bridge columns have high lateral seismic demands due to their low energy dissipation which is undesirable. SMA starter bars which have unique re-centring capability against seismic loading are applied in this study. Nonlinear-static analyses show that self-centring precast bridge columns with SMA bars have superior performance in terms of energy dissipation and residual displacement.
