Descripción
The present paper reports the results of an investigation regarding the design of a method for visually grading sawn timber of Argentinean Eucalyptus grandis. An empirical research project with four samples of beams and one sample of boards subjected to bending, one sample of boards subjected to tension and one sample of specimens subjected to compression, was carried out. The results obtained with specimens in structural sizes show the influence of the more important strength and stiffness reducing growth characteristics and allow to analyse different strength, stiffness and density profiles in comparison with the international strength class system established in the European standard EN 338. The research also reveals particularities for this timber species as the high ratio of modulus of elasticity and strength to density, in comparison with other deciduous species, among others.
Dieser Beitrag fasst die Ergebnisse einer Studie zusammen, in der die Mglichkeiten einer visuellen Festigkeitssortierung von Eucalyptus grandis aus Argentinien untersucht wurden. Die Untersuchung umfasste vier Teilstichproben mit Kanthlzern und eine Teilstichprobe mit Brettern in Biegeversuchen und jeweils eine Teilstichprobe mit Zug- bzw. Druckprfkrpern. Die Ergebnisse der Versuche mit Prfkrpern in Bauholzabmessungen zeigen den Einfluss der wichtigsten visuellen Sortierparameter und erlauben die Einteilung von Bauholz aus Eucalyptus grandis in unterschiedliche Festigkeitsklassen nach EN 338. Die vorliegende Studie zeigt darber hinaus besondere Eigenschaften dieser Laubholzart wie das hohe Verh ltnis von Elastizitätsmodul und Festigkeit zur Rohdichte.
