Simulation RC column with ultra high performance fiber reinforced concrete under compression load in Abaqus

In this tutorial, the Simulation RC column with ultra-high performance fiber reinforced concrete under a compression load in Abaqus has been investigated. The next generation of concrete, Ultra-High Performance Fibre Reinforced Concrete (UHP-FRC), exhibits exceptional mechanical characteristics. UHP-FRC has a compressive strength exceeding 150 MPa, tensile strength in the range of 8-12 MPa, and fracture energy of several orders of magnitudes of traditional concrete. The UHPFRC column is modeled as a three-dimensional solid part. The bars and strips are modeled as three-dimensional wire parts. You can see the figures of the assembled parts below

Nonlinear behavior of concrete has been defined using a built-in concrete damage plasticity  (CDP) model available in ABAQUS. CDP model can be used to model the behavior of plain or  RC under different loading conditions. CDP model is selected because of several distinguishing features; it allows for separate yield strengths, strain rates, and damage parameters in tension and compression.  Additionally, the CDP model provides an advanced representation of various concrete types using a  set of adjustable parameters that can be measured experimentally. These parameters are used mainly to define the yield surface and flow rule in the three-dimensional space of stresses. The tension and compression damage parameters are used to predict the damage under the compression test. The general static step is appropriate for this type of analysis. The surface to surface interaction with contact property is used between rigid bodies and concrete columns. The bars and strips are embedded inside the concrete host. The fixed boundary condition is used for the bottom rigid body and displacement with amplitude for the top rigid body is applied. The mesh has a good effect on the output results

After the simulation, all results such as stress, strain, tensile damage, compression damage, force-displacement diagram,…are obtainable. You can see some figures for the results below
