John Harding to present Trada pavilion at IASS 2013

John Harding of the RCD team will be presenting our work on the Trada pavilion at the International Associate for Shell and Spatial Structures symposium in Wroclaw, Poland on the 23rd September 2013. The talk, simply titled The TRADA Pavilion – A Timber Plate Funicular Shell will be given as part of the session dedicated to Structural Morphology – Faceted and origami structures.

Structural form finding using zero-length springs with dynamic mass

Paper presented at the International Association for Shell and Spatial Structures Symposium, 2011. Abstract:

“This paper describes a new method for the form-finding of funicular structures in two or three dimensions using a zero-length spring system with dynamic nodal masses. The resulting found geometry consists of purely axial forces under self-weight, with zero bending moment at nodes for both shells and tension net forms. A real-time solver using semi-implicit Euler integration with viscous damping is used to achieve system equilibrium. By using a real-time solver, the designer is able to alter the gravitational field or apply new point loads without re-starting the analysis, leading to an interactive experience in generating design options. The advantages of this method over existing approaches are discussed, with its successful application in a recent real case-study project also shown.”
