摘要:
基于前期RC框架及CFRP布加固完好RC框架的水平低周反复荷载试验研究,采用有限元软件SAP2000对该试验进行Pushover分析,结果表明模拟结果与试验值基本相符.以此为基础,通过定义材料的弹性模量(刚度)变化,来表达RC框架的损伤程度,从而建立CFRP布加固损伤钢筋混凝土框架结构的有限元分析模型,继而对该模型进行了Pushover分析,研究考虑损伤参数的CFRP布加固RC框架结构抗震性能,计算结果表明,损伤程度既大幅度减小加固框架的延性,也降低加固框架的极限承载力,验证了笔者分析方法的可行性与合理性.
Abstract:
Based on the previous work of the horizontal low cyclic test study on RC frame and RC frame rein-forced with CFRP sheets,the Pushover analysis about these tests is carried out by using the FEA softwareSAP2000,and the analysis result shows a good consistency with the test result. On this basis,the FEA modelof the damaged RC frame reinforced with CFRP sheets is established,where the damage degree of RC framecan be expressed by defining the material modulus.Then,the Pushover analysis is carried out to study theseismic performance of the RC frame strengthened with CFRP sheet. The results show that the ductility andbear capacity of the frame will decrease with the increment of the damage degree. The feasibility and the ra-tionality of the proposed analysis method are verified in this paper.
