Topology optimization considering self‐weight

Abstract

Abstract In civil engineering self‐weight loading usually represents the preponderant load case and shall therefore be considered in structural optimization. The present study investigates numerical topology optimization of structural stiffness with a bound on disposable amount of material. A customized topology optimization routine based on Sequential Quadratic Programming was built and is examined by means of known benchmark problems complemented by consideration of self‐weight. This study aims to highlight the relevance of consideration of self‐weight in resource efficient structural design by demonstrating its impact on the optimal structural layout.
