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 robustness of the test method based on a single 3D off-axis prismatic specimen for the simultaneous identification of the orthotropic stiffness components of clear wood is addressed. In this method, the specimen is consecutively submitted to uniaxial compression

Abstract The aim of this study is to obtain the elastic constants of Eucalyptus globulus Labill required for any numerical model. Two methods were used for this: the propagation of ultrasound waves and mechanical compression tests. The same test specimens

Abstract This paper describes theoretical and experimental work undertaken to obtain a structural model for assessment of historical Latin-American vertically laminated planked timber arches, as built by the Spanish, mainly in the seventeenth and eighteenth centuries. Many such arches still

Abstract A new way of using resin test models for teaching the structural behaviour of common building elements is presented. It is proposed that a combination of several tools be used. By recording experimental tests with high definition cameras and

Abstract The constitutive models used for wood and timber have been formulated in different scales. The term clear wood corresponds to the macroscopic scale, where the orthotropic elastic model is commonly used. This model, which is typically applied to local

Abstract Experimental results of eight short-term tests of the HSB® (Habitat System Beton) timber–concrete connection system are presented. The specimens were compressive double shear tested according to EN 26891:1991, placing two connectors per shear plane. The ultimate shear force and
