相邻结构-地基-土相互作用的分支模态实用研究
RESEARCH ON PRACTICAL METHOD OF BRANCHED MODE FOR NEIGHBORING STRUCTURES FOUNDATION SOIL INTERACTION SYSTEM
【摘要】 本文在提出模态综合二步分析法研究相邻结构-地基-土相互作用的基础上,采用振动特性和实际结构相同的模拟结构,求得上、下部之间的耦合项,将耦合项和地震动一起组成修正地震动,以此作为刚性基础的结构抗震分析的地震输入。本文为利用专业程序进行相邻结构-地基-土相互作用抗震分析提供了新的途径。
【Abstract】 IN this paper,a two step method for the neighboring structures foundation soil interaction system based on the branched mode method is proposed.According to the inertia coupling of the superstructure and the foundation soil system,the modified earthquake ground motions can be obtained,which can be used as the earthquake inputs for the analysis of seismic responses of the structure with rigid bases.Thus,the neighboring structures foundation soil interaction system can be analyzed by the specialized program.
