Abstract: In order to study the seismic performances of steel reinforced concrete beam-column joints strengthened with AFRP sheets,this paper analyzes the effect of different rehabilitation schemes and different stirrups ratio in the joint core area by the experimental method,and a new anchoring method is presented. The experimental results show that the failure model of strengthened joints with AFRP is turned from brittleness failure to ductility failure,the ultimate strength and displacement are improved remarkably,the biggest increase value are 53.40% and 43.29% respectively,the energy dissipation capability can be increased 0.3~2.3 times;using X type AFRP sheets anchor in the joint core area is an effective anchorage method of seismic retrofitting.
