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。
In order to discuss the seismic effect of prefabricated bridge piers in earthquake zones,three concrete composite specimens with inserted steel tube and prestressed steel strand were fabricated.Quasi-static tests were conduct to investigate the cyclic behavior. Based on the finite element analysis software ADINA, an entity model was built to test its mechanical properties under cyclic load. The experimental results and calculated results fit well. Results indicate that higher prestressing gave greater flexural strength to the composite columns with prestressing and better energy absorption capacity.
