Abaqus tutorials Abaqus simulation and modeling
The Cyclic Test Simulation of Concrete-Filled Steel Column in Abaqus-Validation Analysis has been done in this tutorial. The steel box column, ribs, and stiffener plates are modeled as three-dimensional shell parts. The two concrete blocks are modeled as three-dimensional solid parts. You can see the figures of the assembled parts below
Concrete-damaged plasticity is selected to model concrete behavior under cyclic loading. The concrete damage plasticity material model represents a constitutive model based on a combination of the theory of plasticity and the theory of damage mechanics. This material model is often used in solving geotechnical problems due to its realistic description of the mechanical behavior of concrete material. The elastic-plastic model is considered for the steel material
The analysis is done in two stages, in the first step, the axial load is applied through a static step, and in the second step, the cyclic load is applied to the column. The weld contact model is considered among all steel parts and surface-to-surface contact among the other parts. The proper mesh and boundary conditions are assigned to all parts.
After the simulation, all results such as stress, strain, failure zones, damage, validate force-displacement, or Hysteresis diagram are available. You can see some figures for the results below
