| 摘 要： | 为了在地基阻抗力的计算中能考虑基础动力阻抗函数频率相关性和避免反复进行傅里叶变换,采用地基阻抗力的时域差分计算方法,进行了基于通用有限元软件的结构时程分析程序二次开发,增加了考虑土-结构相互作用效应的结构动力响应时程分析计算模块．对圆盘基础上的多层结构在三维地震激励下的响应进行了数值计算和分析．数值模型结果表明,该方法物理意义明确,能反映土-结构相互作用耦合体系的基础动力阻抗对激振频率的依赖性．

| Abstract: | To take into account the frequency dependency of foundation impedance and avoid repeated Fourier transform, a time-domain difference approach for calculating the ground resisting forces was introduced by the authors. The software programs of structure history analysis were re-developed based on general FEM software, and the dynamic history analysis module of considering the soil-structure interaction effect was included. Finally, multilayer frame with circular foundation on the surface of layered soil media... |
