摘要
地震响应的分析方法主要有一维地震反应分析法和二维动力有限元法,但均不能考虑地震过程中地基系统的振动对形函数的影响。对此较详细地叙述了动态有限元求解地震响应的过程,同时算例表明了动态有限元法求解场地地震响应的合理性,具有一定的理论意义和实用价值。
The popular method of seismic response analysis includes one-dimensional seismic analysis and two-dimensional dynamic finite element method. Whereas ,both of them can't take into account of the influence of vibration to shape function. It this paper, the detailed procedure of analyzing free site seismic response with SRDFEM is provided . The example proved SRDFEM is better than the other seismic response analysis methods. The theoretical significance and practice value is obvious.
