| 摘 要： | 在结构进行地震响应时程分析时,必须首先确定结构的计算模型,以便确立结构的层间刚度。在地震作用下,结构计算模型是结构进行地震响应时分析的主体,由几何模型和物理模型两部分组成。其中几何模型反映了结构计算模型的几何构成,物理模型反映了材料或构件的力学性能。目前在工程上框架结构常用的计算模型主要有层间模型、杆系模型和杆系-层间模型。针对这三种模型进行全面的分析,并对它们的优缺点展开论述。

| Abstract: | In the earthquake response time-history analysis,it is essential to define the computational model for the convenience of the establishment of the stiffness between the floors.Under the seismic action,the computational model is the principal part for earthquake response analysis,and is composed of the geometric model and the physical model.The geometric model depicts the configuration of a structure;and the physical model describes the parameters of the materials.The three models commonly used in the engineering are storey model,beam-column element model,and member relative storey model.The article carries on the comprehensive analysis of these computational models,and discusses their advantages and disadvantages. |
