Long-span roofs have held significant importance in both architectural and engineering fields, evolving alongside technological advancements in materials and their intrinsic properties. The concept of gridshell emerged within this framework as a lightweight, form-resistant structural typology capable of spanning large distances with minimal material thickness and weight. This revolutionary aspect enabled gridshells to be widespread worldwide, especially where lightness and transparency were paramount design criteria. The membrane-like structural behaviour of gridshells involves the high degree of structural efficiency of these structures, but also results in a propensity for buckling instability, which have been studied over time. The need to adapt gridshells to existing structures as well as ensuring accessibility has led gridshells to be designed with free-edges.
