In this tutorial, the Simulation cyclic loading of a steel beam-column joint filled with the UHPC and welded stiffeners in Abaqus has been done. The Ultra-High-Performance-Concrete is modeled as a three-dimensional solid part. The steel beam and column are modeled as three-dimensional shell parts. The stiffeners are modeled as three-dimensional solid parts. You can see a figure of the assembled parts below

To model the UHPC material, the Concrete Damage Plasticity is a good choice. 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 tension and compression data are used as input parameters in this model and also damage. To model steel behavior two models are selected, first elastic-isotropic plasticity with ductile damage, second the combined hardening model. In the ductile damage method, two main mechanisms can cause the fracture of a ductile metal: ductile fracture due to the nucleation, growth, and coalescence of voids; and shear fracture due to shear band localization. Based on phenomenological observations, these two mechanisms call for different forms of criteria for the onset of damage. In the second model, the yield surface is changed during the analysis
Both static and dynamic procedures can be used. The weld contact or perfect contact is assumed among all surfaces. The general contact with friction behavior is considered also. The proper boundary conditions, loads, and mesh are assigned. The mesh should be fine to achieve the correct results
After the simulation, all results such as stress, strain, damage, failure, progressive failure of the stiffeners, column deformation, tension damage, and other results are available. You can see some figures for the results below
