Abstract Timber gridshell structures get their shape by curving on site initially straight timber laths. This curving process produces stresses in the laths that can easily reach values close to the allowable ones. These initial bending stresses are partially reduced

II Latin American Congress of Timber Structures + II Ibero-Latin American Congress of Timber in Construction (CLEM+CIMAD 2017), Buenos Aires, Argentina.
Abstract The necessary revision of the construction processes in search of more sustainable solutions leads to the use of high efficiency structural systems and environmen-friendly materials. In this sense, timber gridshells represent a solution of great interest for lightweight roofs

Abstract The term clear wood corresponds to the macroscopic scale, where the orthotropic elastic model is commonly used. This model is defined by a compliance matrix composed of nine parameters, the elongations and angular distortions of which are uncoupled. The

Abstract In this work, the identifiability of orthotropic stiffness components of clear wood from a single off-axis compression test was investigated. The material characterisation strategy was based on anisotropic elasticity. Moreover, it requires 3D full-field measurements which can be provided
