Concrete Beam With Reinforcement Bars

Application ID: 10440

Concrete structures almost always contain reinforcements in the shape of steel bars ("rebars"). In COMSOL, individual rebars can be modeled by adding a Truss interface to the Solid interface used for the concrete. The solid mesh for the concrete and the rebar mesh can be independent, since the displacements are mapped from within the solids onto the rebar at a certain position.

This model is included as an example in the following products:
