Abstract
Overview
Parametric Design is a powerful design approach that has been widely applied to architectural design in recent years; it is essentially a computational design method distinguished by rule-algorithmic design and multi-solution generation, which can aid in the creation of complex and distinctive designs. Topology Optimization is a technology that optimizes structures by considering design criteria such as applied loads, supports, available domain design, materials, and cost. Its use early in the design phase allows it to produce designs with lowest mass and maximum stiffness. The key to every project’s success is that it be well-designed and structurally assessed. The goal of every construction is to be created intelligently, safely, and as light as feasible. Structural engineers attempt to design with lowest mass, maximum stiffness, and the best structural analysis without regard for design form, whereas architects aim for a good form and distinctive design even if the structure system is not in perfect condition.
Research Problem
Topology optimization has been applied widely in the mechanical and structural fields, and it needs a strong programming background to be involved in architecture, especially in lightweight structures. Finding a basic framework that helps architects easily apply topology optimization in various lightweight structures is rare.
