Form-finding structures
… engineers in the examination of their optimal form. Through the elimination of bending and shear forces in the structure, less material and reinforcement is needed. By minimizing the use of materials, a form that is economical, sustainable and aesthetically attractive emerges. However, this …

Form-finding of elastic gridshells
Elastic gridshells are obtained by elastic deformation of an initially flat grid into a three-dimensional shell-like geometry and were first implemented in architecture in the 1970's. Their mechanical behaviour, which includes aspects of both a continuous shell and a network of elastic rods, is …

Mixed Isogeometric Form Finding Of Lightweight Structures
… to the supports by pure tension forces. The form finding process plays a crucial role for these non conventional structures. Thus starting from a detailed analysis of the state of the art, in the present work the attention has been given on the Force Density Method and the Updated Reference …

Free form finding of grid shell structures
… can have a great impact on its structural performance. This thesis presents a numerical implementation that finds the funicular form of grid shell structures. Two methods are implemented for the form finding: the potential energy method (PEM) and the force density method (FDM). The PEM, …

Definitions of robust structural geometries : metrics and form finding
… and thus can be described as a function of its form; in other words, as a function of topology, geometry and member properties. This thesis investigates the relationship between both a structure's geometry and topology, and robustness. Two quantitative metrics are proposed to quantify a …

Form finding of structural reused material trusses with graphic statics
Reuse of structural steel elements is an active area of research that has great potential and is relatively unexplored due to a lack of design methods. This thesis presents a design framework that uses graphic statics to automatically generate truss designs based on a library of preexisting …

Evolutionary Based Methodology for Form -Finding and Design of Tensegrity Structures
The capability of the new form-finding method is further extended to provide a total design package which can both create and optimize tensegrity structures, by adding structural analysis and optimization criteria to fitness evaluation. As an example, tensegrity towers for mobile communication are …

The constrained geometry of structures : optimization methods for inverse form-finding design
This dissertation aims to improve form-finding workflows by giving more control on the obtained shapes to the designer. Traditional direct form-finding allows the designer to generate shapes for structures that need to verify a mechanical equilibrium when built; however, it produces shapes that are …

Structural grid shell design with Islamic pattern topologies
… patterns, pioneered centuries ago as a dominant form of ornamentation in Islamic architecture, represent an abundant source of possible topologies and geometries that can be explored in the preliminary design of discrete structures. This diverse design space motivates the coupling between Islamic …

Material-based design computation
The institutionalized separation between form, structure and material, deeply embedded in modernist design theory, paralleled by a methodological partitioning between modeling, analysis and fabrication, resulted in geometric-driven form generation. Such prioritization of form over material was …

In Tension: Computational exploration of the design space of tensile network structures
… structures is generally challenging since their form cannot be arbitrarily defined. Instead a process of form-finding must be used to establish a geometry where all edges of the network carry only tensile forces. Physical models and computational methods can be used for the form-finding of …
