Lattice shell methodologies

Abstract

This paper outlines a working methodology for the parametric development of lattice shell structures combining surface topology and form-finding with the material constraints of straight lath members woven into a geodesic network. By employing non-uniform grid spacing, a wider typology of spatial types can be employed than can be achieved with traditional flat-matt lattice shell construction. As a parametric design tool and working methodology, some of the heavy lifting in form-finding and geodesic analysis can be off-loaded to the tool, such that a more comprehensive attention can be placed on other design criteria such as spatial development and environmental response while maintaining the elegance and economy of lattice shells. © 2014, The Association for Computer-Aided Architectural Design Research in Asia (CAADRIA), Hong Kong.
