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.
