Geometry and statics of optimal freeform gridshells

Abstract

We present our recent results on the geometric and static optimization of freeform load-bearing architectural skins. An efficient design strategy is the use of planar cladding panels supported by a prismatic framework substructure with optimized static performance. We show how these structures can be achieved discretizing membranes where principal stress and curvature directions coincide, and the absolute principal stresses are minimized. We outline then a design workflow and we provide some architectural examples.
