Comportamiento mecánico de piezas de madera de pino silvestre de pequeña escuadría sometidas a compresión longitudinal a las fibras = Mechanical behavior of small pine wood pieces subjected to a longitudinal - compressive stress to the fibers

This paper presents an experimental study of the compression behaviour of small pine wood pieces subjected to a longitudinal - compressive stress to the fibers. The mechanical properties obtained are associated with this type of load. The correlations that can be used successfully have been analysed and the concordance between the values obtained with those estimated by the visual grading rules of sawn timber for structural use has been tested. To this end, 11 small pine wood pieces (27x140x300mm) have been tested, subjected to a longitudinal - compressive stress to the fibers. The wood pieces tested are ME1 according to visual classification of UNE 56544 and C27 according to mechanical classification of UNE-EN 1912. The results of the analysis of correlations are presented in the conclusions.
