Abstract:By experiment on beamcolumn joints strengthened by gluedsteel under low cyclic reversal load, the shearcarrying 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 shearcarrying capacity formula of strengthened RC frame joint core is deduced, then the formula is confirmed with the experiment result.
Keywords:frame joint; joint strengthening; glued steel; shear capacity
