桥梁非线性地震反应分析若干问题研究现状

State-of-the-art of nonlinear seismic response analysis of RC bridge

评述了钢筋混凝土桥墩非线性地震反应分析模型与损伤评估、桩－土－桥梁结构动力相互作用试验与理论研究和伸缩缝处的碰撞效应等问题的研究现状，指出了进一步的发展趋势．

Some subjects on nonlinear seismic response analysis of RC bridge are reviewed, which include analysis model and damage assessment of RC piers, model tests and theoretic researches on pile-soil-structure interaction and pounding effects at expansion joints during earthquake. Recent trends about them are also discussed.
