矩形空心钢筋混凝土桥墩抗震性能试验研究综述

Overview of Experimental Studies on Seismic Performance of Rectangular Hollow Reinforced Concrete Bridge Piers

桥墩的抗震性能试验是桥梁抗震分析的基础性研究工作。考虑到空心截面的优越性和地震时地面运动的多维性,通过拟静力试验研究双向水平地震作用下矩形空心钢筋混凝土桥墩的抗震性能具有十分重要的意义。文章从单向水平地震作用下桥墩的抗震性能、双向水平地震作用下桥墩的抗震性能、单双向水平地震作用下桥墩抗震性能的比较这三个方面进行了综述。

The test on seismic performance of bridge piers is the basic research work of the bridge seismic analysis.Taking into account of the advantages of hollow sections,and the multi-dimensional nature of earthquake ground motion,through the quasi-static test,the research of rectangular hollow reinforced concrete bridge piers under biaxial loading is of great significance.From seismic performance of bridge piers under one-way loading,seismic performance of bridge piers under biaxial loading,and comparison of seismic performance of bridge piers under one-way loading and under biaxial loading,the paper makes a comprehensive analysis.
