Caracterizacion estructural de la madera de Pinus radiata D. Don del Pais Vasco (España) acorde a las modificaciones normativas

Abstract

In the last decades in Europe the promulgation of Practice Codes, Directives and Harmonised Standards of obliged fulfilment for the member countries was promoted. They affect to wood in construction and are essential to improve the material in the structural use. Due to the dynamic character proper of standards, and necessary for their functionality, these suffer modifications in the time that are necessary to check in the really existing material. In this work, a representative sampling on one of the usual species of wood in the construction in Spain, as it is the radiata pine, was carried out, looking for the veracity of the available material in the market both in qualities and sections. The standard methodology stipulated for the characterization was applied. Additionally, in each piece, the visual classification criteria established in the Spanish standard UNE 56.544 for the estimation of the strength grades, was applied. The results set forth the conclusions obtained after the application of the last changes of the regulation for the determination of mechanical properties, which are involved in the analyses of the structural characterization of timber and determine the final strength assignation.
