Topology optimization is a free-form approach to designing efficient structural layouts. Although demonstrated repeatedly in literature for its ability to identify creative, high performance designs, it is also well known that solutions may be complex and significantly more challenging to fabricate, driving up construction costs. Such costs are typically a governing metric in the design of large-scale structures, such as building systems, and so should be integrated within the structural optimization process. This work examines constructability in topology optimization of truss structures by incorporating cost metrics directly into the design formulation. Past work in this area is leveraged, and further integrated with stress and stability limit constraints to ensure solutions are both cost effective and satisfy structural demands. The algorithms are implemented on static structural systems, and the trade-offs among material usage, constructability, and structural performance are examined.
