Abstract
In this paper, beam ends of beam-slab-column joints installed in reinforced concrete structures are simulated using ABAQUS FEM analysis software. The simulation work is carried out under the monotonic loading. The damage factor in the plastic-damage model is adopted for describing the damage state of concrete. The failure characteristics, the distribution of cracks on the top side of slab are discussed according to the simulation results. The stresses of longitudinal bars in the slab along with different distances between the longitudinal bar and the beam are given. In reliability assessment of the numerical model, the effects of slab thickness and slab reinforcement ratio on flexural behavior of beam-slab cooperative working are conducted further more.
