Experimental study on structural performance of precast RC beam-column joints

Abstract

Research and development on a new precast concrete system that beam-column joints are manufactured as the precast concrete has been conducted for the purpose of more efficient use of precast concrete technology. In this study, the loading test is conducted for beamcolumn joint specimens to investigate the structural performance. From the test results, no large differences between precast and cast-in-situ specimens can be found out in terms of failure progress, shear force - drift angle curve, deformation components and damping factor. It can be recognized that the structural performance of precast beam-column joints shows the same performance of cast-in-situ joints.
