Abstract
The use of computational parametric design is known as algorithm-aided design. While designers generally rely on intuition and expertise to solve design challenges, computational design aims to enhance this process by codifying design decisions using computer language.
In this study, a useful tool that considers the structural aspects of a rectangular cross section of beam element was proposed. The process was conducted using the algorithm-aided design tool Grasshopper software. It involved determining a variable cross section of beam by facilitating the design phase. The proposed methodology can be particularly useful for practical applications, where numerous drawings have to be covered. In this scenario, the several cross sections gener- ated by the software can alter various numbers of steel bars, ties and hoops. For upcoming CAD design proposals, it is suggested this procedure for automatically processing the results: extracting a wireframe and producing cross sections.
Three-dimensional finite elements now support the cross-section extraction. The skeletonization and vowelization of a finite element- and density-based topology optimization form the basis of the wireframe extraction. The geometrical parameters of each selected beam profile are then established utilizing at least square loss optimization and shape averaging based on image pro- cessing. Finally, a model that may be transformed into a parametric CAD model is accessible for use in future design work.
