| 摘 要： | 本文研究了非线性地基土与非线性多层剪切型结构相互作用体系的问题,其中上部结构恢复力模式为刚度有退化的三线性模型,下部地基土刚度假定为有退化的双线性模型,阻尼采用Veletsos模式。对于层数较多的结构,文中提出可结合使用Holzer方法,从而使计算更为简便。最后,对一多层剪切型结构假定几种地基土刚度进行了计算,并对计算结果进行了分析和讨论。

| Abstract: | In this paper we discuss on the soil-structure interaction with nonlinear founda-tion soil and nonlinear MDF shear structure which is modelled as springswith de-grading trilinear stiffness, but the foundation soil is modelled as springs with de-grading bilinear stiffness, and Veletsos damping is accepted. The numerical analysisof the multi-story building structure may be easier if the above mentioned methodwill be combined with Holzer technique. Examples are given for a multi-storybuilding which is modelled as a multi-story shear system based on foundation soilwith sevaral types of the nonlinear stiffness, and the numerical results arediscussed. |
