Abstract:Based on the recent international research on the concrete beamcolumn joints reinforced with FRP,reasonable antiseismic reinforcement method and calculating outline for designing are presented,and three joints confined with FRP and an unconfined joint are tested.The results of experiment indicate that the antiseismic capacity of joints reinforced with the method is evidently improved.
Keywords:concrete confined with FRP; beamcolumn joints; reinforcing; seismic performance
