In this paper, the finite element model of FRP reinforced concrete frame structure is established, and the seismic performance characteristics of CFRP bars and GFRP Bars concrete frame models are analyzed, such as stiffness degradation, strength attenuation, energy dissipation capacity, etc. The stiffness of CFRP reinforced concrete frame model is obviously greater than that of CFRP reinforced concrete frame model. The stiffness degradation curves of the two FRP reinforced concrete frame models are consistent, and the strength attenuation and energy dissipation capacity of GFRP reinforced concrete frame structure are better than that of CFRP reinforced concrete frame structure.

本文建立了 FRP 钢筋混凝土框架结构的有限元模型，分析了 CFRP 钢筋和 GFRP Bars 混凝土框架模型的抗震性能特征，如刚度退化、强度衰减、消能能力等。 CFRP 钢筋混凝土框架模型的 CFRP 钢筋混凝土框架模型明显大于 CFRP 钢筋混凝土框架模型。两种FRP钢筋混凝土框架模型刚度退化曲线一致，GFRP钢筋混凝土框架结构的强度衰减和耗能能力优于CFRP钢筋混凝土框架结构。
