【摘要】：为研究装配式桥墩在地震区的抗震效果,设计3个内插钢管及预应力钢绞线的混凝土试件,通过拟静态试验探讨预制复合柱的循环反应;通过实体有限元软件ADINA对装配式混凝土桥墩进行模拟,测试其在循环荷载下的力学性能,模型试验结果与计算结果吻合较好,表明高预应力组合柱拥有更高的强度和更好的吸收能量能力。
[Abstract]:In order to study the seismic effect of prefabricated piers in earthquake region, three concrete specimens of steel tubes and prestressed steel strands were designed, and the cyclic response of prefabricated composite columns was studied by quasi-static test. The physical finite element software ADINA is used to simulate the assembled concrete pier and its mechanical properties under cyclic load are tested. The results of the model test are in good agreement with the calculated results. It shows that high prestressed composite columns have higher strength and better energy absorption capacity.
