IRREGULAR CABLE-NETS

Unlike conventional cable nets that typically use evenly spaced cables laid out in an orthogonal-grid, introducing irregular patterns into the form-finding process of cable structures enables designs with non-directional grids and varying cable concentration. These characteristics are investigated in this project as a mean of expanding the design space of such systems and of achieving a more equal force distribution in the cable network. A comparison between the structural performance of cable nets with orthogonal and Voronoi cable meshes is performed that evaluates how these different cable arrangements transfer forces within the network and determines the structural mass required by each system to achieve comparable deflections. Furthermore, this project explores the cable discontinuity characteristic of Voronoi grids as a feature that enables cable section optimization throughout the system. A similar optimization strategy is also applied to orthogonal cable nets and a study comparing possible weight reduction through section optimization is presented.
