In this tutorial, the Simulation compression test of the UHPFRC column with internal CFRP box in Abaqus has been investigated. The Ultra-High-Performance-Fiber-Reinforced concrete is modeled as a three-dimensional solid part. The CFRP internal box is modeled as a three-dimensional shell part. Two rigid bodies are used as supporter and body that apply the force. You can see a figure of the assembled parts below
Extensive research and development efforts, over the past three decades, to improve properties ofconcrete have led to the emergence of ultra high performance concrete(UHPC). UHPC possesses very high compressive strength, good tensile strength, enhanced toughness, and durability properties. However one of the main drawbacks of UHPC is its brittleness property. To overcome brittleness of UHPC, fibers are often added to UHPC and this type of concrete is referred to as ultra high performance fiber reinforced concrete(UHPFRC). Addition of fibers to UHPC can significantly improve its ductility, fracture toughness, and energy absorption capacity. The Concrete damaged plasticity model is used to consider true behavior of the concrete column. The CFRP box consider as an elastic material with Hashin’s damage criterion to predict the damage that happens during the simulation. The general static step with some changes in the convergence model is used. The perfect contact is considered between concrete and CFRP. The fixed boundary condition is assigned to the bottom rigid plate and displacement to the top plate. The mesh should be fine to obtain correct results
After the simulation, all results such as stress, strain, damage, force-displacement diagram is obtainable. You can see some figures for the results below
