【摘要】 上部结构、基础与地基为一整体结构系统,在水平地震作用下考虑这一系统中三者共同作用的相互影响可以做到对结构的准确分析。利用结构有限元分析软件ANSYS对上部框架结构、桩筏基础及软土地基进行整体建模,并对其进行地震反应谱分析,以分析共同作用下框架结构的抗震性能,并与不考虑共同作用的计算结果进行对比。提出了对结构设计的合理建议,可供工程设计参考。更多还原

【Abstract】 Superstructure,foundation and soft of the system as a whole,the level of seismic action in this system to consider the interaction between the three can work together to achieve an accurate analysis of the structure.Uses finite element analysis software ANSYS,the upper part of the framework Structure,pile foundation and soft for a whole raft model,and its seismic response spectrum analysis,to analyze the framework under the combined action of the seismic performance and interaction with the calculation does not take into account the results were compared.The rational design of proposals for engineering design is suggested by this paper.更多还原
