What is Computational Design?

If you’ve arrived at this blog, you will probably have had some exposure to the concept of ‘computational design’.  You may also have heard some of the related terms that fall under this heading – ‘parametric design’, ‘algorithmic design’, ‘generative design’ and so on.  As computational design is still a relatively young and evolving field the meanings of these terms can be a little vague and are used by different practitioners in different ways. This article presents the vision of computational design that we have in Ramboll and the role that we see it having in the future of the industry.  This is what *we* mean by computational design.

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.”
