چکیده

Since the test method for compression strength perpendicular to the grain was changed from a partial area to a full area loading test, strength values for softwood in EN 338 were significantly reduced. Consequently, a change in Eurocode 5 was necessary to ensure an equivalent resistance level in compression perpendicular to the grain. Experimental results are presented with wood in compression perpendicular to the grain. A numerical model is also presented. This model was used to establish a rule of calculation proposed at the P21A-Committee of the technical and construction equipment standardization office (BNTEC). RÉSUMÉ. Depuis que la méthode de caractérisation de la résistance en compression transversale du bois a été modifiée, les valeurs de résistances des bois résineux ont été considérablement réduite dans la norme EN338. Par conséquent, une modification de l Eurocode 5 était nécessaire pour assurer un niveau équivalent de résistance. Les résultats expérimentaux d essais en compression perpendiculaire aux fibres sont présentés. Un modèle numérique est également présenté. Ce modèle a permis d établir une règle de calcul qui a été proposé au niveau de la commission P21A du Bureau de Normalisation des Techniques et des Équipements de la Construction (BNTEC).

Bearing Strength Capacity of Continuous Supported Timber Beams: Unified Approach for Test Methods and Structural Design Codes

Bearing or compressive-strength capacity perpendicular to the grain of timber beams is a troublesome issue. Not only do many different load cases occur in practice that are not covered by structural timber design codes, but also these codes provide only a basic provision and vary throughout continents. Code design rules require the standardized compressive or bearing strength to be determined b...

Strength Properties of Low Moisture Content Southern Pine

Contemporary engineering design practices in the United States require information on the strength of lumber for moisture contents as low as 4 percent. Efficient design of experimental studies on lumber properties at low moisture contents requires a better understanding of the basic mechanisms controlling moisture-property relationships. Studies were conducted on the effect of moisture content ...
