| 摘 要： | 为了研究轴向力对外露式刚性柱脚抗震性能的影响并提高外露式柱脚抗震设计的可靠性,文中利用Ansys有限元软件,针对外露式柱脚连接节点的抗震性能进行了数值模拟研究,将有无轴向力作用的两组柱脚试件抗震性能进行对比,分析了其在往复荷载作用下的破坏特征、滞回特性、骨架曲线、延性及耗能指标。根据数值模拟结果,提出水平地震荷载作用下轴向力会加速试件割线刚度的退化,给出一些抗震设计建议,为今后的工程设计和研究提供参考。

| Abstract: | In order to test the influence of axial force on the seismic performance of expoesd column footing connection joint and to improve its anti-seismic reliability,the thesis here uses Ansys finite element software to do a numerical simulation research on the seismic performance of exposed footing connection and compares the different performances of two column footings with and without axial force by analysing its failure features,hysterestic behavior,ductility and capability of energy dissipation.According to... |
