Seismic Behavior of Π-Shaped Connector RC Beam–Column Joints: Experimental and Numerical Investigation
Numerous existing RC frame buildings in China suffer from seismic deficiencies. This paper proposes a novel Π-shaped connector connection joint for the rapid strengthening of existing beam–column joints: steel plates are wrapped around existing columns, and Π-shaped connectors are welded to link new beam reinforcement....
