本文对一个实际工程进行了土-结构动力相互作用的三维有限元分析。分析中使用了通用有限元程序Ansys。土的本构关系选用常用的等效线性模型。在有限元程序中实现了土体的粘性边界。讨论了土性、结构刚度、激励等参数对SSI体系动力特性、地震反应及相互作用效应的影响。
Three-dimensional finite element analysis in time domain on dynamic soil-structure interaction of a practical engineering is carried out in this paper. General-purpose finite element program ANSYS is used in the analysis. Commonly used equivalent linearity model is chosen as constitutive relation of soil. Viscous boundary of soil is implemented in ANSYS program. The influences of parameters are discussed, such as soil property and the rigidity of structure, excitation, on dynamic characteristics, seismic response and interaction effect of SSI system.
