Topology optimization considering self-weight

Masarczyk, Daniela
Kuhl, Detlef

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.
