Abstract

For this investigation, topology optimization was used as a tool to determine the optimal reinforcement for reinforced
concrete beam. The topology optimization process was based on a unit finite element cell with layers of concrete and steel.
The thickness of the reinforced steel layer of this unit cell was then adjusted when the concrete layer could not carry the
tensile or compressive stress. At the same time, unit cells which carried very low stress were eliminated. The process was
performed iteratively to create a topology of reinforced concrete beam which satisfied design conditions.
