In this tutorial, the Simulation compression test of the concrete column with and without steel reinforcement-Compression test- has been investigated. The concrete column is modeled as a three-dimensional solid part. The steel reinforcements are modeled as wire parts and two rigid bodies as boundary zone and hydraulic jack. You can see a figure of the assembled parts below
Two separated analysis has been performed. In the first analysis, the compression test of the short concrete column without steel rebars is done. In the second analysis, the compression test with steel reinforcement is done. The force capacity is the aim of this simulation and after the simulation, they can be obtained from two models.
Concrete Damaged Plasticity is selected for the concrete model to consider concrete behavior. 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. To model steel behavior, elastic-plastic material data is used. The general static step for both analyses with general contact to consider all contacts in the contact domain is selected. The fixed boundary condition is assigned to the bottom rigid body and displacement as a smooth load to the top rigid body. The mesh should be fine for both simulations
After the simulations, all results such as stress, plastic strain, force, displacements,…are available. The force capacity is compared between the two models and the effect of the steel reinforcement to increase the force capacity is obvious. The maximum force for the column contains steel reinforcement is much bigger than the column without that. You can see some figures for the results below
