Abstract:Reinforced concrete (RC) beam‐column joints often present brittle shear failure in the core area. The objective of the study is to study the effects of stirrup ratio and axial load ratio on the shear capacity of geometrically similar beam‐column joints having different structural sizes. In this work, a series of 3D mesoscale simulations on the shear failure of RC beam‐column joints were conducted and validated, in which the concrete heterogeneity was considered explicitly. The simulation results indicate that … Show more
