摘要:
通过对5根PHC管桩进行低周往复加载,分析其受力状态、破坏形态、承载力、滞回曲线、延性等抗震性能指标,研究桩径、有效预应力及配置非预应力筋对PHC管桩抗震性能的影响.结果表明:PHC管桩的抗震性能随着桩径的增加而降低;随着桩身有效预应力的提高,试件破坏的脆性特征及刚度退化现象减弱,抗震性能有所改善;而配置一定数量的非预应力筋可使其抗震性能得到明显改善.
Abstract:
In order to investigate the effect of the pile ’s diameter,pile body ’s effeetive prestress and configu-ration of a certain number of non prestressed reinforcement on seismic behavior of PHC pile,five PHC pileswere tested under low cyclic loading. The damage characteristic,bearing capacity, hysteretic curve and duc-tility were analyzed. It is shown that the seismic performance of PHC pile was reduced with the increase of thepile’s diameter and with the improvement of pile body’s effective prestress. The configuration of a certainnumber of non prestressed reinforcement can effectively improve the level of the pile ’s seismic performance.
