ABSTRACT

Beam-column joint in reinforced concrete (RC) structure is a critical element that needs to be monitored continuously throughout its service life. The beam-column connection acts as the core component that receives moment transfer from adjacent elements. Consequently, the integrity of the RC beam-column joint reduces when subjected to load over time. This study investigates the damage of RC beam-column joint subjected to static load until failure using acoustic emission (AE) signal strength. The size of the RC joint sample was composed of 300mm x 200mm x 600mm, 200mm x 200mm x 1200mm and 1500mm x 500mm x 300mm for beam, column and foundation respectively. The vertical loading was applied to the beam at 530mm distances from the column surface. Four sensors were used at specified positions at the beam and column surfaces. It was found that the increment of load intensity results in intensified acoustic emission signal strength.
