Abstract: In various embodiments, a room-based design application automatically generates a design for a floor structure of a building. In operation, the room-based design application generates blocks representing portions of the floor structure that are delineated by walls based on a room plan included in a computer-aided design of the building. The room-based design application modifies the blocks based on a spanning length to generate partitions. Each partition represents a different portion of the floor structure that can be spanned by a structural element that has the spanning length in at least one direction. Based on the partitions, the room-based design application determines wall classifications for the walls. The room-based design application generates at least a portion of the design for the floor structure based on the wall classifications and the partitions.

Abstract: In various embodiments, a grid-based design application automatically generates a design for a structural system of a building. In operation, the grid-based design application generates a structural grid based on a region within a computer-aided design of the building. Subsequently, the grid-based design application applies the structural grid to the region to generate a gridded region. The grid-based design application computes a set of spanning directions based on the gridded region. The grid-based design application then generates at least a portion of the design for the structural system based on the set of spanning directions and the gridded region.
