摘要
由拉格朗日方程导出地基-结构系统地震响应分析的动力方程,利用突变模型分析了系统对地震响应的复杂过程,并分析了振幅响应的跳跃现象和“路径”效应等非线性动力特性,得出了有意义的结论。分析结果对地基-结构系统的参数设计有一定的参考价值。
Dynamic equations for seismic response analysis of foundation-structure system are derived from Lagrange equation. The analyses of complex seismic process and nonlinear dynamic characteristics, such as suddenly jumping and path effect of amplitude response, are made with catastrophe model. Some useful conclusions are drawn; and the analytic results are of good value to parameters design of foundation-structure system.
