Abstract Elastic timber gridshells are built by bending small cross-section, long and good quality timber laths on site to the desired shape. This procedure enables double curvature structures of great aesthetic appearance and high structural efficiency. Despite their interest, few

Abstract Timber lattice shells are multi-layered structures of great interest for medium and long span lightweight solutions in structural and aesthetic terms. They are constructed by bending initially straight laths. This curving process can lead to high initial stresses in

Abstract The prediction of the fracture behaviour through reliable and practical criteria in the design of structural timber elements and connections has become of great importance and demands a proper fracture characterization of the material. Eucalyptus globulus Labill is envisioned
