Computational Slab Panelization

Panelization Strategies from the Timber Morphology Research Project

A new slab panelization strategy was developed for the ICD’s multi-directional hollow slab system. Through this method, it is ensured that the panels can be placed on regular and irregular arrays of columns. Multiple factors influence the outlining and detailing of panels such as size limitations, structural performance, and assembly sequences.

The strategy consist on the following processes:

Axis Placement: A pill-packing algorithm is used for evenly distributing the slab’s longitudinal axis

Outline Placement: A line Vornoi diagram is used to generate curved outlines. These are post-processed into linear polygons

"Rectangularization": The panel outlines are dynamically pushed to their fabrication space limits to reduce offcuts in panels

Structural analysis: Each panel is ranked from lower to higher deflection

Topology and Sequencing: Connection types are calculated and their assembly order established according to deflection ranks

Joint generation: The stepped joints of the system are generated according to the assembly order and modeled for fabrication
