Architectural Design Optimisation in Reticulated Free-Form Canopies

Abstract

The search for the structural form of reticulated roofs is significant in interdisciplinary Architectural Design optimisation. Combining parametric design with structural logic influences the visual perception of the shape by choosing the most suitable technical solutions. Therefore, the divisions of reticulated structures should be determined to pursue structural, material and fabrication advancement. Structural divisions of free-formed canopies should simultaneously be solved in architectural and structural design at an early stage. Choosing a proper design becomes a complicated process, requiring the ability to select a type of production and rationalise technical solutions mainly due to the computer-aided design supported by algorithmic tools. Based on searching for optimal geometrical divisions, the case study investigates the differences between planar quadrilateral and triangular mesh panelisation. The study concludes the assets and flaws of both geometry shaping methods of reticulated structures based on minimal weight and fabrication aspects. The study concludes that implementing the manufacturing method of the chosen type of gridshells divisions into the architectural design optimisation enhances the resulting free-form structures at the early design stage.

Generative Shaping in Search of Material and Structural Optimisation of Small Structural Forms

“…The optimisation algorithm can also be used to carry out static calculations. The advantage is the non-stereotypical thinking of the program and the ability to carry out hundreds of calculation variants in a short time (Stefańska & Rokicki, 2022).…”

Relationship of Form and Structure in Santiago Calatrava’s Pylon Bridges

“…Architecture (...) often demands more from the designer than he is able to achieve, wrote Sigfried Giedion in the mid-twentieth century (Giedion 1968, p. 10). In the 21st century, there has been a change in the design activity in architecture and construction, which is noticeable mainly thanks to digital tools (Rokicki, Stefańska 2022). Digital parametric tools offered by several modern computer programs are becoming increasingly popular in architectural design (Januszkiewicz 2016, p. 57).…”
