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 simulation of the viscoelastic artificial boundary is carried out with the large-scale finite element software ANSYS. The calculation results show that ANSYS has good accuracy in absorbing the boundary or fluctuating input when solving the structural-foundation dynamic interaction problem. The modal analysis of a plane frame structure shows that the effect of structure-foundation interaction on the structure is obvious.
