Finite element analysis of punching shear of concrete slabs using damaged plasticity model in ABAQUS
Highlights Description of the concrete damaged plasticity model used in ABAQUS. Calibration of the material parameters in the adopted model. Simulation of five different concrete slabs with the calibrated material model. Good agreement between test and FEA responses for all slab specimens.
Abstract Nonlinear finite element analyses of reinforced concrete slab-column connections under static and pseudo-dynamic loadings were conducted to investigate their failures modes in terms of ultimate load and cracking patterns. The 3D finite element analyses (FEA) were performed with the appropriate modeling of element size and mesh, and the constitutive modeling of concrete. The material parameters of the damaged plasticity model in ABAQUS were calibrated based on the test results of an interior slab-column connection. The predictive capability of the calibrated model was demonstrated by simulating different slab-column connections without shear reinforcement. Interior slab-column specimens under static loading, interior specimens under static and reversed cyclic loadings, and edge specimens under static and horizontal loadings were examined. The comparison between experimental and numerical results indicates that the calibrated model properly predicts the punching shear response of the slabs.
