| 摘 要： | 通过ANSYS软件建立异形柱框架及矩形柱框架结构弹塑性空间分析模型,并将宁河地震波两个水平方向分量及作者计算获得的扭转分量同时输入结构,对其进行弹塑性时程分析,研究结构在水平地震波及考虑扭转地震波分量时最大位移反应的差异,并将异形柱结构与普通框架结构的地震反应进行了对比.结果表明,多维地震波对异形柱框架结构的影响大于普通框架结构,是对地震扭转分量非常敏感的结构体系,设计时应充分考虑扭转分量对结构效应的增大,提高异形柱结构的抗震安全性.

| Abstract: | The spatial analysis model of special-shaped column and rectangle column frame structure are established in ANSYS. The seismic elasto-plastic time-history analysis of the structures subjected to Ninghe wave with two horizontal components and torsional component are carried out, analyzing the peak displacement response and horizontal-torsional response of special-shaped column frame, and comparing the seismic response between special-shaped column and rectangle column frame. Simulations show that the seismic... |
