Abstract:By experiment on beamcolumn joints strengthened by gluedsteel under low cyclic reversal load, the shearcarrying capacity of strengthened RC frame joint core is studied, and the load bearing mechanism of strengthened joints is analyzed. Based on the code formula, the shearcarrying capacity formula of strengthened RC frame joint core is deduced, then the formula is confirmed with the experiment result.
