本文研究桩基-非线性框剪结构相互作用体系的地震反应。其中上部框架和剪力墙结构分别用门型单元和四弹簧墙单元进行分析；桩基阻抗函数通过单桩阻抗和动力相互作用因于求得。采用频-时域混合法求解体系的动力方程，本文研究了在桩基-框剪结构相互作用体系地震反应分析中，桩基阻抗的频率相关性对结构地震反应的影响，并从土体剪切波速和地震波强度两个方面，研究了土-桩-结构相互作用对框剪结构地震反应的影响。
In this paper, we study the seismic response of the pile-nonlinear frame-shear interaction system. Among them, the upper frame and the shear wall structure are respectively analyzed by the door-type unit and the four-spring-wall unit; the impedance function of the pile foundation is obtained through the interaction between the impedance and the dynamic force of the single pile. In this paper, the influence of the frequency dependence of pile impedance on the seismic response of the structure is studied in the seismic response analysis of pile-frame shear interaction system. Shear wave velocity and seismic intensity, the effect of soil-pile-structure interaction on the seismic response of frame-shear structure was studied.
