摘要

为了研究钢筋混凝土空心桥墩的抗震性能及影响因素,对5个较大比例的钢筋混凝土空心桥墩进行了水平低周往复加载试验,评价了其整体抗震性能,并分析了配筋率、轴压比、箍筋间距对桥墩承载能力、延性、刚度等抗震性能的影响。研究发现:钢筋混凝土空心桥墩抗震性能良好,配筋率、轴压比、箍筋间距对其的影响符合一般钢筋混凝土理论,空心桥墩大大减少了材料,可以安全应用到工程中。

Abstract

In order to further study the seismic behavior of reinforced concrete hollow bridge columns and factors influencing,five reinforced concrete hollow bridge columns models with large ratio were built and tested to failure under the combined action of constant axial load and reversed cyclic laterl load.The aim of this paper is to evaluate seismic performance of all the five models,and variables included longitudinal reinforcement ratio,spiral reinforcement ratio,axial load ratio,influence seismic performance,such as failure mode,hysteretic behavior,load-carrying capacity,ductility. Analysis of the experimental results suggest that the seismic performance of reinforced concrete hollow bridge columns is great,influence of variables obey the theory of reinforcement concrete.With such hollow pier in engineering,we can save material dramtically,and have enough security of safety.
