For safety reasons, ductile failure in timber connections with dowel-type fasteners is always recommended. It has usually been assumed that it can be achieved by fulfilling minimum spacing requirements between fasteners. However, recent works address the need to account for brittle failure modes (namely splitting, row-shear, and block and plug-shear) in connections loaded parallel-to-the-grain in an explicit manner, in order to evaluate them and achieve the desired ductility. This article describes the brittle failure modes and reviews the existing calculation models proposed by several authors ¿ some of them included in standards. Finally, the performance of these models is assessed against an extensive database of tests gathered from the literature following a comprehensive methodology.

Wood, as a natural heterogeneous material, is a challenging material to simulate. This work presents an algorithm to model both its elastic and post-elastic responses. It allows to model different compression and tension elastic and failure behaviors in both material directions, parallel and perpendicular to the grain. It employs two different strategies: a sequential application of different failure criteria, and the modeling of post-elastic response by means of damage and stress reduction parameters. The proposed algorithm is applied to spruce in two experimental cases with different loadings and failure modes. When reasonable mesh density and increment size are used, the obtained results are in good agreement with the experimental results. The proposed algorithm has been programmed in the commercial software ABAQUS. However, it may be easily applied to different platforms or wood species.

Several methods for determining in-plane shear properties of anisotropic materials (i.e. fibre reinforced composite materials and natural wood) based on flexural loading have been proposed. One of those methods is the off-axis flexural test that considers unidirectional composite materials subject to three-point bending loading. As a result of the anisotropic behaviour, unidirectional off-axis laminates subjected to flexure present a bending¿twisting coupling that may cause, in the case of 3-point bending loading, a lift-off of the specimen on the fixture supports. Such specimen lift-off has been considered one of the critical features to be considered on the mentioned experimental method. Besides geometrical parameters, material elastic constants, as longitudinal, transversal and shear elastic moduli, influence the validity to use this method for characterising in-plane shear properties. On that sense, an analytical approach for studying the material conditions for which the application of the off-axis 3P-B test is adequate is presented.

Recent biaxial experiments on clear-spruce wood allow to have a more complete understanding of fracture behavior of wood. An elliptic failure surface, like that of Tsai¿Wu, has been previously proposed as a failure surface. Previous works in this area have shown the need for further developments. In this study a new failure model that accounts for existing different couplings and interactions in the longitudinal compressive and tensional domains is presented. The model is based on the fracture behavior of clear spruce wood and related experimental works. The model is more accurate compared to existing phenomenological models.

Many different phenomenological failure criteria have been proposed. These type of criteria do not explain the mechanism of failure itself. They merely identify failure (yes or no) and are usually regarded in practice as a simple and reliable tool for design. Most of them were developed for composite materials, but are extensively applied for wood. In this study, existing phenomenological strength criteria for orthotropic materials were applied to clear wood data. Instead of fitting the criteria to available experimental data, the criteria were used to predict failure of biaxial tests based on uniaxial strength. This procedure is closer to practice, and hence an answer to the question ¿is there any reliable failure criterion for wood?¿ Predictability of the criteria was assessed using normalisation procedure, and statistical significance of the difference of the means analysed. Based on the results, it can be concluded that a general criterion cannot be applied to predict failure, but should be chosen according to the biaxial stress state.

En la primera parte de este trabajo se realiza una revisión de los distintos modelos de fallo de la madera en estados de carga multiaxial propuestos hasta el momento. A continuación se hace un análisis estadístico del ajuste de dichos criterios a resultados experimentales, encontrados en la literatura, de ensayos realizados en madera de abeto blanco bajo distintas condiciones de carga. Finalmente se propone un nuevo criterio de fallo no continuo con el cual, sin aumentar el número de parámetros requeridos por otros criterios, se obtiene un mejor ajuste a los datos experimentales.

As a natural resource, an efficient use of wood should be also a requirement for structural timber design, but the usual structural solid sections do not achieve the required optimal behaviour. The performance of the structural elements (serviceability and strength) depends not only on the material properties, but mainly on the moment of inertia of the cross section. The Timber Construction Institute of Technische Universität Dresden has developed a process for the manufacture of structural wood profiles. The resulting profiles combine economy, an efficient use of the material and optimal structural performance. They are externally reinforced with composite fibres, which improve the mechanical characteristics of the wood and protect it from weathering. The available experimental tests to axial loading show the outstanding properties of this new technology. Herein, the preliminary model developed to obtain the axial strength of longitudinally compressed tubes is presented. Two different analytical algorithms are discussed and applied. The model adequately predicts the axial strength of fibre reinforced wood profiles. The analytical results are within an error less than 10% to the available experimental results, with a mean error ratio less than 3%.

La sociedad es cada vez más consciente del valor de los recursos naturales, y por ello demanda un uso eficiente de los mismos. Ése ha de ser también un objetivo al diseñar estructuras de madera. Habitualmente se emplean secciones macizas, circulares o rectangulares, que no obtienen un comportamiento óptimo, y que por tanto no aprovechan al máximo las propiedades y posibilidades de la madera. En el Instituto de Construcción en Madera de la Universidad Tecnológica de Dresde se ha desarrollado un proceso para la fabricación de perfiles estructurales de madera eficientes. Aprovechando el efecto memoria de la madera densificada, paneles de madera se transforman fácilmente en todo tipo de secciones prismáticas, cerradas o abiertas. El perfil resultante combina economía, uso eficiente del material y rendimiento estructural óptimo. Junto con un mínimo refuerzo exterior de fibras, se mejoran las características mecánicas de la madera, y se la protege de las inclemencias atmosféricas. Los perfiles así realizados poseen unas excepcionales características resistentes, como demuestran los ensayos experimentales realizados. Se presenta el modelo desarrollado para el análisis estructural de este nuevo concepto de aplicación de la madera. Basado en teorías clásicas para materiales compuestos, describe adecuadamente el comportamiento estructural de la madera reforzada con fibras: predice con un error inferior al 10% los resultados experimentales

Associate Professor of the Department of Building Construction, Services and Structures of the University of Navarra. Spanish Expert in the Working Group "Connections" of the Eurocode 5, Timber Structures, TC250 / SC5 / WG5.

My current research interests focus on structural design in wood, particularly on the application of new concepts and developments.

I made my doctoral thesis (2001-06, Special Prize of the School of Architecture of the University of Navarra) on semi-rigid steel structural connections, under the assessment of Prof. Bayo. I made a postdoctoral stay at the Technische Universität Dresden (Germany) thanks to a Humboldt Fellowship (2007-08). There I delved into wood construction and collaborated in the development and design of structural tubes made of densified wood.

I later rejoined the University of Navarra, where I led the development of a new line of research in timber construction. I got the support of the Government of Navarre for the creation of the Wood Chair at the university. I am its director since its creation in 2011.

I have published 11 articles in scientific journals included in the Science Citation Index, 8 of them in journals located in the first quartile. I collaborated with Prof. Bayo in the drafting of Chapter XIV, Connections, the current Spanish instruction for the design of steel structures, EAE. I have presented several papers at national and international conferences, one of them invited at the 19th European Conference on Fracture (ECF19, 2012).

Besides collaborating as the Spanish expert in the already named Working Group of the Eurocode 5, I collaborate in a number of committees and actions related to timber construction: Subcommittees CTN140 5 and 6 of CTN56 AENOR. I participate in the COST Action FP1402 "Basis of structural timber design - from research to standards.

I've been Principal Investigator on two Spanish research projects. I have participated as a researcher in national and European research projects and won several research contracts. I collaborate as an evaluator of research projects for several evaluation agencies, and as a reviewer for s number of scientific journals.
