RC beam column joint reinforced with steel plates and rods under vertical load

In this lesson, the analysis of an RC beam column joint reinforced with steel plates and rods under vertical load is The concrete beam-column is modeled as a three-dimensional solid part. The steel bar and strip are modeled as a three-dimensional wire part. The steel plates and rods are modeled as a three-dimensional solid part. Concrete is a very heterogeneous material that shows complex nonlinear mechanical behavior. In addition, it is very difficult to define damage in a concrete structure. In the analysis of concrete structures using the finite element method, material models are used for these purposes. An example of these material models is the concrete damage plasticity material model. This material model combines the yield theory of plasticity and the theory of damage mechanics in order to effectively analyze the concrete structure's behavior. Material parameters identification of the concrete damage plasticity material model is performed in this example. The concrete damaged plasticity can show the tension and compression damage of the beam-column joint after loading. The steel material with elastic-plastic behaviour is considered for all steel reinforcement. To model the damage behaviour of the steel plates and rods, the ductile damage criterion is selected. Both dynamic and static steps can be used in this tutorial; to decrease the time of the simulation, a dynamic explicit step with the mass scale technique is used. The perfect contact, surface-to-surface contact with friction, and embedded region constraint are applied for all parts.
