WebFeb 15, 2024 · The shape of elastic gridshells is determined by form-finding methods, as traditional design methods are inapplicable in this case. Douthe et al. [32], [33], [34] have developed the form-finding algorithm for elastic pre-stressed gridshells, based on the adaptation of the dynamic relaxation method [35]. Another innovative type of form-found ... WebWe develop a discrete differential geometry-based model of elastic gridshell to investigate their form-finding process. Even though the forward process from 2D footprint to 3D gridshell can be captured by physics-based simulation, the inverse problem of obtaining the original footprint given the 3D deformed shape still lacks a generalized method.
