Abstract
This paper introduces a new structural modeling methodology to generate equilibrated, discrete three-dimensional structures, with both compression and tension elements, through geometric transformations and modifications of force polyhedrons. By exploring the geometric properties of polyhedral reciprocal diagrams used in three-dimensional graphic statics, the proposed approach provides a significant amount of control of spatial structures during conceptual design. The presented design examples will demonstrate how this method can be used to discover new three-dimensional structural typologies without any biases towards conventional solutions. They also provide an alternative design strategy for two-dimensional problems.
