Finite Element Analysis of Reinforced Concrete Slab-Rectangular Column Connections Using ABAQUS

Abstract Rectangular columns used in flat-slab structures run the risk of punching shear damage due to stress concentrations, especially when bending moments and vertical forces act together at connections. Using finite element analysis method, existing experiments are numerically simulated using 3D modeling software ABAQUS, describe cracking behavior concrete damaged plasticity model. The accuracy numerical simulation was calibrated by load–displacement curves crack patterns experimental results. study model set up with different moment-to-shear ratios outputs trend average on eccentric force side slab. moment transfer coefficients derived through equation ACI-318 compared code values. A safe range length is proposed reduce from use rectangular columns. This provides a reference for practical design, but more needed support recommendations.
