RESEARCH EXPERIMENT OF THE BEAM-TO-COLUMN JOINT REINFORCED BY CFRP AT NEGATIVE MOMENT AREAS

By the comparison of the connection and reinforced connections’loading tests，this paper aims to analyse the different distance from the side of the beam to CFＲP and the changing influence on the reinforcement effect of connection owning to different layers of CFＲP sheets． The experimental results show that the closer distance from sticking CFＲP to beam edge，the better the consolidation． Conversely，the effect is worse． The more layers of CFＲP sheets，the more effect． But when the layer of the CFＲP sheets is more than 3，the ultimate flexural resistance of the beam-to-column connection will not be obvious．
