Paper Title:
Study on Effect of FRP Reinforced Manners on Seismic Performance of Concrete Frame Structure
  Abstract

Many studies showed that FRP bonded to the concrete beams and column surface can effectively enhance the mechanical properties of members, and FRP reasonably bonded to the beam-column joint area can significantly improve the seismic performance, but not enough studies have been carried out on the overall mechanical properties in structure after the framework members are partially covered with FRP. In this Paper, based on the seismic demand analysis of the concrete frame structure, as well as FRP seismic enforcement strategy, a fiber attachment method has been proposed for FRP seismic reinforcement framework. Taking a two-layer dual-span plane framework as an example, nonlinear static analysis has been carried out on FRP-reinforced framework, the capacity spectrum method has been adopted to assess the seismic performance of reinforced framework and the impact of different FRP-reinforced methods on structural seismic performance has been discussed. The results showed that the method of moderate shear-resistance reinforcement in the joint core area, as well as the beam-column plastic hinge area, can effectively improve the seismic performance of the framework, the application of GFRP reinforcement features higher cost-performance ratio, and the FRP bonding at ± 45º in the joint core area can better the reinforcement effect.
