In this paper by B. D’Amico, and A. Kermani, H. Zhang, a ‘facilitating’ numerical framework is introduced in which, for a given continuous reference shape, a geometrically similar discrete model is found by implementation of a six degree of freedom formulation of the Dynamic Relaxation method, to handle members bending and torsional stiffness.

This paper by Abtin Baghdadi, Mahmoud Heristchian, Harald Kloft has modelled and studied Isler’s eight shells in the fnite element software, Abaqus, as a homogeneous section together with a composite layer to allow for assignment of re-bars of the reinforced concrete material.
In this paper Yang Liu, Helmut Pottmann, Johannes Wallner, Yong-Liang Yang, and Wenping Wang show how to optimize a quad mesh such that its faces become planar, or the mesh becomes even conical.
This paper by Matthias Rippmann and Philippe Block, discusses new ways of digitally generating voussoir geometry for freeform masonry-like vaults.
In this paper by Lorenz Lachauer, Matthias Rippmann, and Philippe Block, a fully digital design process –from form finding to fabrication– for compression-only masonry shells will be presented.
LiABlock_3D by Lucrezia Cascini, Raffaele Gagliardo, and Francesco Portioli, is a novel software tool for the limit equilibrium analysis of masonry structures modelled as assemblages of three-dimensional rigid blocks subjected to live loads and settlements.
This work by Mara Capone, Emanuela Lanzara, Francesco Paolo Antonio Portioli, and Francesco Flore is aimed at designing an inverse hanging shape subdivided into polygonal voussoirs (Voronoi patterns) by relaxing a planar discrete and elastic system, loaded at each point and anchored along its boundary.
This thesis by Dragos Naicu, upon reviewing the design and construction processes of previous timber gridshells, puts forward a structural model that aims to represent the true nature and specifics of single and doublelayered timber gridshells.
