【摘要】 把建筑结构、基础和地基视为一个动力学系统来研究结构的地震反应，并且与工程中应用的刚性地基，以及结构与基础视为一个系统的地震反应进行对比。建立了考虑结构、基础和地基相互作用的地震反应的非线性动力学方程式，并附有算例及对结果进行的分析更多还原

【Abstract】 The seismic reaction of the structure is studied by taking an architectural structure, underlying base and the foundation as one dynamics system, thereupon, which is compared with the rigid foundation, the structure and the underlying base in an engineering application, by being regarded as one system′s seismic reaction. As the result, a non linear dynamics equation is established for mutually seismic reaction under consideration of the structure, underlying base and the foundation, with computed examples and their results being attached hereto.更多还原
