This thesis evaluates particle-spring systems as conceptual design tools in an effort to create efficient grid shell structures. Currently many simulation tools are available to create representations of intricate geometries and forms. However, these forms can become highly complex and challenging upon their realization. A lack of understanding of these forms leads to structures that cannot support their corresponding loads due to their shape, boundary conditions or edge conditions. To create successful grid shells, designers must understand the design principles behind these forms. The goals of this research were achieved through a parametric study that involved manipulating the topology and topography of three global grid shell geometries. It was determined that the ability of particle-spring form finding methods to create good structures is highly dependent on both the mesh type used and the structure's global geometry. A list of implications has been developed and is presented in this work.
