摘要
对于钢筋混凝土框架结构在地震作用下的反应 ,本文采用时程分析法分析结构在弹性阶段的反应和采用弹塑性静力分析法分析结构在弹塑性阶段的反应 ,主要分析了由结构竖向刚度、屈服强度和质量的变化而引起结构在弹性阶段的基底剪力和弹塑性阶段结构延性系数的变化。
In this paper,for the response of reinforced concrete frame structures under earthquake action,time history method is used to analyze the structure in the elastic stage and elasto-plastic static method is used to analyze the structure in the elasto-plastic stage. The variations of the base shear of the structure in the elastic stage and also the ductility factor in the elasto-plastic stage due to the change of the vertical stiffness. yielding strength and mass of the structure are discussed. The object is to provide a guide to transform the qualitative description of the concept to quantitative description in the conceptual design as required in the Code for Seismic Design of Buildings,which will facilitate the application in engineering practice.
