摘要:
总结现行的RC框架结构抗震设计、抗震鉴定标准和震害资料,选取了场地条件、规则程度、混凝土强度以及结构层数4个影响框架结构抗震性能的主要因素进行分析;以7度设防的西南地区典型双跨外廊式教学楼为原型,设置8个分析工况,采用基于位移控制的非线性静力(Pushover)分析方法得到各工况在不同烈度罕遇地震下的最大层间位移角(ISDA),以此为指标对4个框架结构抗震性能影响因素的重要性进行评价分析;最后采用模糊层次分析法,给出了以上影响因素在RC框架结构抗震性能评估中的重要性排序以及初始权重值。
Abstract:
Code for seismic design, standard for seismic appraisal seismic damage data of RC frame structures were summarized, and four main factors (i.e., site condition,irregularity, concrote strength and story number) affecting the seismic behavior of frame structures were analyzed. Based on the prototype of a typical double-span verandah-style teaching building in the south-west area with 7-degree fortification, eight analytical working conditions are set up. The maximum inter-story Displacement Angle (ISDA) of different seismic intensity is obtained by using the nonlinear static (Pushover) analysis method based on displacement control. Based on the ISDA, the importance of the four factors affecting the seismic behavior of the RC frame structure is evaluated and analyzed. The order of importance and the initial weight value of the above factors in the seismic behavior evaluation of RC frame structures are given by fuzzy analytic hierarchy process.
