【 摘 要 】

How to improve the ductility of FRP reinforced concrete frame is the key issue to solve the seismic safety of FRP reinforced concrete frame. Based on the force deformation process and failure characteristics of FRP reinforced concrete frame structure, a FRP reinforced plastic hinge connector was developed and applied to the concrete structure, which can introduce ductility into the FRP reinforced concrete frame structure to improve its seismic performance. Pushover analysis of FRP reinforced concrete frame structure model with FRP reinforced plastic hinge connector was carried out by SAP2000. The shear force-vertex displacement curves of the base under four lateral force loading modes and the variation of the interlayer displacement angle of the structures under rare conditions are obtained. The results of analysis show that the appearance of plastic hinges significantly improves the ductility of FRP reinforced concrete frames.
