STRAIN ANALYSIS ON CONCRETE BEAM-COLUMN JOINTS STRENGTHENED WITH AFRP SHEETS

Abstract

Abstract:

Five steel reinforced concrete beam-column joints strengthened with AFRP sheets and two unstrengthened joints are tested for comparing their influences on seismic performances.Based on the experimental results,the changing law of AFRP sheet strains are analyzed,and a new anchoring method is presented.It is found that the ultimate strength and seismic behavior of the joints strengthened with AFRP are improved remarkably|using X type AFRP sheets anchor in the joint core area is an effective anchorage method for seismic retrofitting.

Key words: AFRP, beam-column joints, strengthening, strain
