建立了结构-地下室-桩-土动力相互作用的运动方程,其中土体采用样条有限元法、样条子域法和半解析无限元法等分析方法,上部结构及多层地下室采用弯剪模型;

• The equation of motion of the strcutural system considering structure ?basement ? piles - soil interaction is built, in which the Spline Finite Element Method,the Spline Subdomain Method and the Semi-Analytical Infinite Element Method areadopted to simulate the soil, and the bending-shear model is used for thesuperstructure and the multistory basement.
