In the reinforced concrete column to footing connection design, the region around the column is exposed to punching shear failure. This is an undesirable failure since it results in a brittle failure and it governs the strength of the footing in column to footing connection. The shear stresses that act around the perimeter of the column tend to punch through the footing and develop a failure surface in the form of a truncated cone or pyramid shape.

    In this research, a nonlinear finite element modelling and analysis of the punching shear capacity of the reinforced concrete column to footing connection is conducted. The modelling of the reinforced concrete footing is based on existing literature on the experimental investigation to support the finite element analysis output. The modelling is conducted by using the ABAQUS software. The material used in modelling is modelled considering the nonlinear effects, for concrete material behaviour defined based on the concrete damage plasticity model and reinforced steel model as an elastic–perfectly plastic material. The validity of finite element analysis has been verified through comparison with available experimental data from other researchers. Four different reinforced concrete columns to footing connections have been model numerically. A systematic parametric study of the material parameters compressive strength and flexural reinforcement ratio is carried out in this research to identify the effects of the material parameters on punching shear strength of footing in column to footing connection.
