Resumen En este trabajo se analiza el comportamiento a compresion de piezas de madera de pino silvestre de pequena escuadria sometidas a un esfuerzo de compresion longitudinal a las fibras. Se han obtenido las propiedades mecanicas asociadas a este tipo de solicitacion, se ha analizado que correlaciones pueden emplearse con exito y se ha comprobado el ajuste de los valores obtenidos con los estimados por las normas de clasificacion visual y resistente de la madera en uso. Para ello se han ensayado a compresion en sentido longitudinal a la fibra y hasta rotura 11 piezas de madera de pino silvestre de pequena escuadria de 27x140x300mm. Las piezas ensayadas son ME1 segun clasificacion visual de UNE 56544 y clasificacion mecanica C27 segun UNE-EN 1912. En las conclusiones se presentan los resultados del analisis de las correlaciones efectuadas en la investigacion. Abstract 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.
