A Simple Approach for Topological Optimization of Concrete Beams

Recently, a numerous topology optimization technique has been reported by the earlier researchers. Within most techniques, a design domain with applied boundary conditions and load case is well defined and used by the design engineers. The design problems in formal optimization problem are rigorously solved using a mathematical program. To the judicious understanding of authors, an optimization through a density-based approach is still in infancy and there only exists limited literature. In this study, a density-based topology-optimized design of plain concrete hammerhead beams was investigated using Autodesk Fusion 360. For this intention, the design example from the literature has been used for topology optimization. Imposing stress limits on the design problem considered in this work is found to create solutions that require significant levels of post-processing prior to construction. The results revealed that the size lessening without affecting its functionality led to saving in building materials within the built world. Also, an interactive density-based topology optimization of concrete beams resulted in new shapes and topology of beams for use in the bridge construction industry.
