摘要
用大型有限元计算软件ANSYS实现了粘弹性人工边界的模拟,计算结果表明,ANSYS在解决结构—地基动力相互作用问题时,无论是吸收边界性能还是波动输入都有很好的精度。对一平面框架结构进行了模态分析,结果表明,结构—地基相互作用对结构的影响是明显的。
The viscous-spring artificial boundary is made by program ANSYS, by which it is proved that both absorbing boundary and seismic input can get precise results. The results of modal analysis on a plane frame structure show that the influence of the structure-foundation interaction on the structure cannot be ignored.
