Abstract

This paper outlines a method of using Finite Element Analysis (FEA) software to study the behavior of materials, geometries, and configurations to create an iterative design feedback loop for generating and refining complex configurations of form-active surfaces. The method integrates technical feedback on structural performance – material stresses, deformations and elastic buckling potential – while respecting design intention and promoting constructability, improved structural performance, and syntactic consistency. Instead of the 2-dimensional (planar) technology which drove modernist analysis towards the structural hyper-rationality of the trabeated system, this new process compiles and synthesizes computational speed, mathematic principles, mechanical knowledge, and material logics within a digital 3-dimensional (spatial) analytical environment in order to realize a new paradigm of constructible complex surface structures. The research focuses on the development of structural performance criteria for form-active structures and interoperability techniques/protocols between advanced CAD systems and advanced structural analysis systems in order to create a fluid design + analysis process of generating and engineering complex form-active designs.
