An implementation of the ground structure method considering buckling and nodal instabilities
The ground structure method is used to find an optimal solution for the layout optimization problem. The problem domain is discretized with a union of highly connected members, which is called a ground structure. The objective typically is to minimize the total volume of material while satisfying …

Macro-element approach for topology optimization of trusses using a ground structure method
In this thesis, the generation of initial ground structures for generic domains in two and three dimensions are discussed. Two methods of discretization are compared: Voronoi-based discretizations and structured quadrilateral discretizations. In addition, a simple and effective member generation …

Shear wall layout optimization for conceptual design of tall buildings
… process with an optimization system involving a ground structure program formulation, a modified evolutionary algorithm, and innovative computational techniques. Unlike existing work that focuses either exclusively on structural performance or architectural layout, this research integrates both. …

Structural optimization: from continuum and ground structures to additive manufacturing
… by giving cheaper, stronger, lighter and safer structures. Gradient--based optimization is the preferred approach in this work, for it consciously improves a design using the gradient information, as opposed to making random guesses. The optimization problem has an internal dependency on …
