Abstract
Parametric Design is a powerful design approach that has been widely applied to architectural design in recent years, it’s essentially a computational design method that can be characterized by rule-algorithmic design and the multi-solution generation that can help to create complex and distinctive designs. Topology Optimization is a technology for developing optimized structures considering design parameters like expected loads, available design space, materials, and cost. Embedded early in the design process, it enables the creation of designs with minimal mass and maximal stiffness. The key to success for any project is to be well-designed and well-structurally analyzed. The aim of designing any structure is to be designed intelligently and responsibly and as light as possible. For this reason, the lightweight structures are selected to be the case study to apply parametric design and topology optimization. Structural engineers aim to design with minimal mass and maximal stiffness and the best structural analysis without concerning the design form, unlike Architects their aim is a good form and distinctive design in case the structure system might not be in the perfect situation, so it will be interesting to apply topology optimization in lightweight structure to have as light as possible structure in addition to the distinctive form.
Therefore, the vision of the research is to try to reach the best situation between design and structural analysis, by using the parametric design patterns that improve the design and form generation and use Topological optimization methods with digital fabrication techniques to reach better structural performance and apply them to lightweight structures, with the aim of testing the effect of using parametric patterns and topology optimization on a lightweight structure with an already existing traditional design. The main aim of the research is to create a framework for applying topology optimization in lightweight structures.
Doing that by first defining lightweight structure types, characteristics, construction materials, and examples, then defining the parametric design approach and its characteristics, limitations, and patterns. And analyzing some applications of parametric design in lightweight structures through a specific set of criteria. Then defining topology optimization in architecture through its definition, characteristics, different methods, algorithm flowchart, software, and several applications of it in architecture. then discussing the new techniques of fabrications that help to apply topology optimization. Then analyzing some case studies of lightweight structures which applied on them topology optimization to create the framework.
This research concludes by creating a framework for applying topology optimization in lightweight structures and applying this framework in a case study (pentagon roman vault).
