| 摘 要： | 地震时地面运动是复杂的多维运动,结构的地震反应也是多维的,因此深入研究多维地震动作用下结构和构件的弹塑性抗震性能具有重要的理论意义和实用价值.本文对3个预应力混凝土空间框架节点进行了多维拟静力试验,对其在不同加载路径下的抗震性能进行了深入研究,试验结果表明,加载路径对试件的抗震性能有着明显的影响.

| Abstract: | The seismic responses of structures and ground motio n are multiple dimensions under earthquake,the research on the elastico-plastic seismic behaviors of structures and members under multi-dimensional earthquake have important theoretical meaning and practical value.The seismic behavior of three prestressed concrete spatial joints subjected to biaxial lateral load reve rsals is experimentally investigated in this paper.The effects of different loa d paths on the seismic behaviors of specimens are studied.Th... |
