This example has done the finite element modeling of the pull-out test of precast wall panels connection in Abaqus. The two precast concrete walls are modeled as three-dimensional solid parts. The reinforcement steel bar and strips are modeled as wire parts. The steel bar as the connectors between two walls are modeled as three-dimensional solid parts. You can see a figure of the assembled parts below
The behavior and possible failure modes of precast wall panel connection under severe loading conditions remain challenging in achieving a reliable connection. Furthermore, the interaction between precast wall panels’ interfaces in terms of shear-slip relationship due to adhesion, friction, clamping stress, and dowel action is complex
To model concrete behavior, the Concrete Damaged Plasticity is selected. Elastic-plastic material data is used to define the steel material.
dynamic explicit step and cohesive interaction method are used. The interaction between two concrete walls is modeled as the surface-to-surface contact, the interaction between the steel bars and concrete wall is assumed as a cohesive model by using stiffness, and damage behavior.
Proper boundary conditions and loads are assigned to all parts. After ending the simulation, all results such as stress, strain, failure, separation, steel bar pull-out, force-displacement diagram, and others are available. you can see some figures for the results below
