Resumo
Topology optimization provides design solutions to several engineering applications and density methods are the most popular approach in this field. However, when it comes to building design, the dimension of the extended domain related to the high of the building provides material concentration at the basis of the building. On the other side the ground structure method provides desirable grid solutions using a highly connected truss in a approach close to size optimization techniques. This work presents a prospective study about the application of both density methods and the ground structure method to conceptual design of buildings and explores desirable manufacturing constraints such as patterns repetition and symmetry. Simulations are developed both in two-dimensional and three-dimensional building configurations, illustrating the potential future applications of this work in the context of building layout optimization.
