Modelling Funicular Structures

Funicular structures are structures whose geometry is based on the funicular polygon, a term from graphic statics. Such structures work mainly with axial forces, almost without bending. Typical examples are arches and cables.

At the IABSE-IASS Symposium 2011 in London, I presented novel parametric tools for structural design in early stages. These have been developed at the Chair for Structural Design, ETH Zurich. Download the paper here.

Based on concepts of graphic statics, custom Grasshopper components have been implemented that allow for the interactive modelling of a planar funicular polygon in Rhino. Straight lines are interpreted as external forces, axial forces in the funicular are represented by tubes, red tubes are in tension, blue tubes are in compression. The tube section is proportional to the magnitude of the axial force.

These tools facilitate intuitive modelling of funicular, hence efficient, structural systems.

3D Printed Stone Vault

At the Design Modelling Symposium in Berlin, a 3d printed vault prototype, designed by Norbert Palz and Ricardo Gomes, has been exibited.

The vaulted structure has been additively fabricated using the d-shape techology, it is 3d printed from an artificial sandstone.

The prototype has been designed using RhinoVAULT.

Padua Pavilion at ETH

Yesterday evening, on the ETH Zurich campus, the Padua Pavilion has been opened. It is a structure made of recycled timber, developed and built in two weeks by students of the studio Tom Emerson.
