To find structure concepts for building spatial designs, structural elements can be added to a spatial design, preferably at the boundaries of the explicitly defined spaces, and these elements can subsequently be optimised via topology optimisation, which is here defined as strategy I. Another strategy (II) is to interpret the total volume of the spatial design as structural mass -so without defined spaces-, and to optimise the distribution of this mass via 3D topology optimisation, most often naturally yielding (open) spaces as well. In this paper, strategy II is extended by including a movable void explicitly. The final aim is to compare strategies I and II, however, some issues exist with movable voids within gradient-based topology optimisation, and future research needs to explore non-gradient based methods first. |
