STUDY ON SEISMIC PERFORMANCE IN THE IN-PLANE AND OUT-OF-PLANE DIRECTION OF RC COLUMNS RETROFITTED BY THE STEEL PLATE SANDWICH METHOD BONDED WITH PC BARS

Abstract

The seismic performance of reinforced concrete (RC) columns retrofitted using the steel plate sandwich method bonded with prestressed PC bars was compared in both in-plane and out-of-plane directions. Therefore, in-plane and out-of-plane bending strength, initial horizontal rigidity, and cumulative energy absorption improved.
