Simulation axial compression of the damaged concrete column with initial residual stress reinforced with CFRP in Abaqus

In this tutorial, the Simulation axial compression of the damaged concrete column with initial residual stress reinforced with CFRP in Abaqus has been investigated. The concrete column is modeled as a three-dimensional solid part. The CFRP box is modeled as a three-dimensional shell part. In the first simulation of the first analysis, the column is modeled under the axial load. The damage and residual stresses from that simulation are written to be used in the second simulation as an initial condition. In the second simulation, the CFRP box is added to the concrete column and it covered the damaged zones of the column. You can see a figure of the assembled parts below

The concrete damaged plasticity model is used to define concrete behavior under axial loading. The Hashin’s damage criterion is used to model CFRP behavior. In the first simulation, two static steps are used, in the first step the axial load is applied and in the second step, the load is deactivated. The fixed boundary condition is assigned to the bottom of the column and axial load to the top surface. After the first simulation, the results such as stress, strain, tensile, and compression damage are achievable. These results should be imported to the second simulation as an initial condition. In the second simulation, the damaged column with initial residual stress is analyzed. The CFRP box is added to the column to cover the damage and increases the force capacity. In the second simulation, the axial load is increased to achieve the failure of the assembled parts.

After the simulation, the results from the first and the second analysis can be compared. You can see some figures for the results below
