EXAMINATION OF STRUCTURAL PERFORMANCE OF PRECAST RC BEAM-COLUMN JOINTS BY LOADING TEST

Abstract

In this study, the structural performance of fully precast reinforced concrete beam-column joints was examined by conducting loading tests while varying the shear capacity in the panel zone, anchorage capacity of reinforcing bars of beam and the ratio of column flexural strength to beam flexural strength (axial force ratio). As a result, the structural performance was identified by comparing the relationship between beam shear force and inter-story drift angle, and between their envelopes. The adaptability of a maximum strength evaluation method was verified and the deformation capacity was identified based on the ductility factor.
