Pseudo-geodesic gridshells

Elastic gridshells are efficient structures covering large spans with little material. They fabricated using a network of straight members deformed into doubly curved shapes. Researchers and builders have used two families remarkable curves to generate planks: geodesic gridshells, where the planks follow lay along tangent plane surface, asymptotic lines orthogonal surface normal. This article proposes concept pseudo-geodesic surface. introduces scaling argument showing that structural efficiency may be twice as much gridshells. is illustrated by parametric study implements linear buckling analysis on various
