Strained Grid Shells

In this paper by Gregory Charles Quinn, Chris J K Williams, and Christoph Gengnagel, a detailed comparison is carried out between established as well as novel erection methods for strained grid shells by means of FE simulations and a 3D-scanned scaled physical model in order to evaluate key performance criteria such as bending stresses during erection and the distance between shell nodes and their spatial target geometry.

Bend Timber Grid shells

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

Timber Gridshells

In this context by Philippe Charest, André Potvin, Claude M. H. Demers, and Sylvain Ménard, there is a renewed interest in systems allowing the materialization of curved surfaces such as timber gridshells, which can be defined as shells with their structures concentrated in strips.

shells of Heinz Isler

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.

LiABlock_3D

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.

Voronoi Pattern

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.

Timber Gridshells

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 double layered timber gridshells.
