摘　　要：自复位桥梁墩柱节点由耗能组件和弹性自复位组件两大部分构成。耗能组件如耗能钢筋、阻尼器等提供足够的耗能能力;弹性自复位组件如无粘结预应力钢筋等可以有效减小震后残余变形。结合自复位桥研究的有关文献,综合分析自复位桥梁墩柱节点试验研究、数值模拟和工程应用方面的现状,提出今后研究发展方向。A Self-centring bridge pier joint consists of energy dissipaters and elastic recovery devices.Energy dissipaters e.g.mild steel bars or dampers can dissipate enough energy;and elastic recovery devices like unbounded post-tensioned tendons can reduce the post earthquake residual displacement.Combined with the research literature about self-centring bridge pier joint,based on a comprehensive analysis of experimental research,numerical simulation and engineering applications,future research direction of self-centring bridge pier joint has been proposed.
