Abstract:
The deformation of the joint core, beam ends, column ends, and the strains of the longitudinal reinforcement of the beams were measured by testing five full-scale reinforced concrete (RC) exterior
beam-column joints. The hysteretic behaviors, crack patterns, and failure modes of the specimens were analyzed and compared with the results of the numerical simulations. The results demonstrated that the damage-plasticity model, based on the thermodynamic processes, provided a reasonable assessment of the beam-column joints. In the plastic stage, the deformation at the column tip—caused by the shear deformation of the joint core—was significant. The shear deformation was affected by the beam depth and volume-stirrup ratio of the joints. In addition, the evolution of the proportion of the shear force resisted by truss mechanism and diagonal strut mechanism was derived through the equilibrium equation of force, and considering the bond degradation of the longitudinal reinforcement in the joint core.
