In this tutorial, the Simulation Behavior of Beam-Column Joints Strengthened With UHPFRC under axial load in Abaqus has been investigated. The beam-column joint is modeled as three-dimensional solid part. The UHPFRC parts are modeled as three-dimensional solid as reinforcement. The strips and bars are modeled as three-dimensional wire parts. You can see figures of the assembled parts below
The concrete material with CDP material model is used to model concrete beam-column joint under axial loading. 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. The steel material with elastic-plastic data is used to model strips and bars behavior. The CDP model also is used to model UHPFRC during the analysis. The UHPFRC can be used at the joint areas to increase beam-column joint ductility and can improved the the tensile stress capacity. The general static step with some changes in the convergence model to avoid early not convergence. The ideal or perfect contact is used to model contact between UHPFRC reinforcement and beam-column joint. The embedded region is considered for the steel members inside the concrete host. The pressure load is applied to the top surface of the column and displacement to the end of the beam. The fixed boundary condition is assigned to the bottom surface of the column. The mesh should be fine to achieve the good results
After the simulation, all results such as stress, strain, tensile and compression damage, and … are available. You can see some figures for the results below
