“…Developments in manufacturing technology led to the steady growth of curvilinear geometries, but are not altering the technological systems used in the construction sector [39]. According to the new approaches to designing gridshell divisions [40][41][42][43], it is essential to search for the shape of the curvilinear geometry and search for the structural divisions that allow an equilibrium state to be reached. For this reason, the study attempts to investigate different types of structural meshes in free curvilinear canopy structures and to recognise other boundary conditions of their usage.…”

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.

“…The three most important factors influencing the selection of panels with quadrilateral or triangular geometry are distinguished: design method, the technology of execution, and architectural quality. The presented conclusions were made based on the analysis of research works from recent years [17,5,15,18]. architectural quality -a larger ratio of the surface area of the rod structural elements in comparison to the quadrilateral grids, which is equivalent to less translucency -higher translucency and interior illumination thanks to a smaller ratio of structural elements is a covering material.…”

The search for the form optimization of reticulated roof structures is a significant aspect in Architectural Engineering and Construction section. It consists of reflecting the intended aesthetic effect as well as an attempt to choose the most suitable technical solutions. Therefore the divisions of reticulated structures should be determined to pursuit of structural, material and technique of fabrication advancement. In contemporary construction practice, understanding how curved shapes describe the form becomes an significant design aspect. Structural divisions of free-formed canopies should be solved in architectural and structural design simultaneously at an early stage of designing. The choice of proper designing method becomes a complicated process, requiring the ability to selecting type of production and rationalize technical solutions mainly due to the computer aided design supported by algorithmic tools. The paper research analyzes curvilinear structures of canopies in search of optimal structures of geometrical divisions. Case study is based on reticulated roof structures with triangular and quadrilateral panelization. In recent twenty years, the most common and accessible solutions for free-form canopies are triangular divisions due to the ability to use flat glass panels. Panelized Quadrilateral surfaces, facilitate the fabrication process in many aspects, surpassing triangular panels. Their main disadvantage was the design of quadrilateral flat panel mesh. The finding of the study conclude assets and flows of both methods of shaping the geometry of reticulated roof structures based on material and technology of fabrication aspects. The study conclude that the crucial designing method is to determine the manufacturing technology in the early stage of architectural optimization.

“…The digitization of the design process allows the integration of various technical disciplines. Thanks to integrating digital systems, it is possible to design in tight cooperation between multiple branches, interdependently searching for rational solutions, which often are a creative compromise for the target solutions [8]. The interdisciplinary design of gridshells leads to sophisticated structural systems that are often characterized by unobvious, complex shapes, with their geometries referring to free fractal structures, sometimes going beyond Euclidean geometry paradigms [9].…”

The design of unique gridshell forms has become a key factor in effective interdisciplinary designing solutions, both architecturally aesthetic and structurally efficient. Modern bionic tendencies allow designers to implement organic shapes through proportion and mimicking the biological, developmental process by understanding the logic of the structural forms occurring in Nature. The improvement of digital tools based on algorithmic codes has enabled architects to implement their bold designs based on Nature’s technologies’ logic. The purpose of the research was to identify how the mathematical algorithms found in Nature collaborate with parametric designing influence structural optimization of the free-form structures. The Delaunay divisions used in the gridshells form-finding were obtained through various generative modeling algorithms. The case studies demonstrate how mathematical algorithms, such as structural dynamic relaxation, can support architectural aesthetic and structural optimization processes. The paper concludes that proper generative algorithmic design can compromise design diversity and search for efficiency.
