Simulation dynamic compression test of a steel column with the UHPC core in interaction with a concrete foundation in Abaqus

In this tutorial, the Simulation dynamic compression test of a steel column with the UHPC core in interaction with a concrete foundation in Abaqus has been investigated. The concrete foundation and column are modeled as three-dimensional solid parts. The steel column and steel stiffener angles are modeled as shell parts. The steel bed and bolts are modeled as three-dimensional solid parts. The steel reinforcements are modeled as the wire parts. You can see some figures of the assembled parts below

To model normal and Ultra-High-Performance-Concrete, the Concrete Damaged Plasticity model is selected. 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. Slump is a test to measure the plasticity of concrete. Slump test is the most commonly used method of measuring the consistency of concrete which can be employed either in the laboratory or at the site of work. It is not a suitable method for very wet or very dry concrete

For all steel parts in the simulation, the elastic-plastic model, and damage behavior are selected. The steel reinforcements are embedded inside the concrete foundation. The dynamic explicit step and static general can be used. The connection among all parts are considered, and besides that, a general contact with frictional behavior is selected. The proper mesh and boundaries are assigned to all parts

After the simulation, all results such as stress, strain, tension and compression damage, failure, force-displacement diagram, and others are available. you can see some figures for the results below
