Article
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 stra...

El splitting es el fallo frágil producido en las uniones de madera debido a una rotura por tracción en la dirección perpendicular a la fibra. Diversas investigaciones y normativas proponen métodos diferentes para calcular la resistencia de una unión ante el splitting. En la investigación que se presenta se han comparado los métodos descritos por: l...
Conference Paper
The paper deals with the first works for the application of the Hole-Drilling technique on timber structures in service. The final objective of the research is the deduction of the stresses in structural elements of the Architectural Heritage. The method involves glued strain gages at the surface of a structural element. At least three strain gages...
Article
The development of accurate structural modelling techniques is required to promote the use of timber as a renewable alternative to other structural materials. Due to their remarkable influence on the global behaviour of a timber structure, an accurate description of the performance of structural connections is needed. Particularly in the case of mo...

Article
Finite element models tend to overestimate the actual elastic response of structural timber connections. The paper shows how such overprediction relates to the modelling of the contact between fasteners and timber. The use of a control parameter called stiffness contact is proposed. After an experimental campaign, a method to determine it, based on...
Chapter
Timber is becoming an increasingly important construction material all over the world. However, there is usually a lack of knowledge regarding its usage. This chapter provides background information on the failure of timber structures, and especially of timber connections, which are crucial to structural timber design. Wood is a complicated materi...
Conference Paper
Si bien el estudio de los arcos de mampostería se viene desarrollando desde el siglo XII, los distintos métodos de cálculo no tienen en consideración la influencia del módulo elástico. Por ello, el presente trabajo tiene como finalidad estudiar la influencia del módulo elástico en el estudio de los arcos de mampostería, mediante la utilización de...

In order to model wood connections, the contact between the different elements of the joint must be taken into account in a realistic way. However, the mechanical behaviour in the contact areas is quite different from that usually assumed, and obtained from experiments in areas where there is no contact. Therefore, the use of the elastic modulus gi...

Structural timber connections with metallic mechanical require careful detailing. They may be designed for capacities defined by the splitting capacity of the timber and not by ductile failure of the fasteners, which has not been the case in the studies done for GFRP dowels. This work analyses the possibility and potential for the use of different...
Thesis
Full-text available
La madera es un material ortótropo, con distinta elasticidad en su tres direcciones principales, cuya gran relación entre resistencia y masa aprovechamos para obtener eficientes elementos estructurales. Sin embargo, la eficiencia de estas estructuras está limitada por los grandes márgenes de seguridad que tienen este tipo de estructuras debido entr...
Conference Paper
Full-text available
Some decades ago, a different understanding of timber structural behavior was introduced. Among others, Madsen concluded that timber was different from wood. Timber, a useful construction material produced from logs, is a different material from defect-free wood. That change of concept was applied to standards and related experimental procedures.

El principal objetivo del proyecto es la generación de una metodología automatizada para el cálculo estructural cuasi-estático de arcos de fábrica que permita estudiar paso a paso el comportamiento de un arco de fábrica, desde la formación del primer mecanismo hasta el colapso. Dejando la puerta abierta al estudio sísmico de éste tipo de estructuras:
