【 摘 要 】

In order to promote the rapid development of FRP reinforced concrete structure engineering application, it is very important to study the failure mechanism and seismic performance of FRP reinforced concrete frame structure. In this paper, a 1/4 scale specimen model of GFRP reinforced concrete structure is designed and manufactured according to similarity theory. The finite element model of the shaking table test specimen of GFRP reinforced concrete frame structure is established by using SAP2000 finite element analysis software. The validity of the finite element model is verified by comparing the natural vibration period with the first six modes. Then, the model is defined as a non-linear dynamic time-history load condition, and the dynamic elastic-plastic time-history analysis is carried out to obtain the dynamic performance indexes of the model under different levels of earthquake, such as acceleration response, inter-story displacement angle and floor shear force.
