In this tutorial, the Simulation compression test of a RC column with spiral CFRP with fully damaged behaviour in Abaqus has been investigated. The concrete column is modeled as a three-dimensional solid part. The spiral CFRP is modeled as a three-dimensional solid part. The steel bar is modeled as a wire part. You can see a figure of the assembled parts below
To model concrete behaviour, the Concrete Damaged plasticity is used. The model is a continuum, plasticity-based, damage model for concrete. It assumes that the main two failure mechanisms are tensile cracking and compressive crushing of the concrete material.The concrete damaged plasticity model in Abaqus provides a general capability for modeling concrete and other quasi-brittle materials in all types of structures, and it is designed for applications in which concrete is subjected to monotonic, cyclic, and/or dynamic loading under low confining pressures. Two model of the column with fully damaged and without fully damaged are simulated. The elasic material as engineering constant data is considered for the spiral CFRP. The elastic-plastic material with ductile damage criterion is selected for the steel reinforcement
The dynamic explicit step is appropriate for this type of analysis. The CFRP and steel reinforcements are embedded inside the concrete column. The proper boundary conditions, load and mesh are applied to the all parts
After the simulation, all resutls such as stress, strain, tensile, and compressive damage, fully damage, and force-displacement diagram is available. You can see some figures for the results below
