Multifactorial Study of Last resistance to Parallel tensión to the Fiber in Samples of Guadua angustifolia Kunth Estudio multifactorial de resistencia ultima a tensión paralela a la fibra en muestras de guadua angustifolia Kunth

Abstract

This artide presents the Parallel tensión to the Fiber Strength in Samples of Guadua angustifolia specimens from four areas of Pitalito Huila in relation to factors such as base, intermedíate or hig-her area, performed by multifactorial analysis of variance. The methodology for cutting the culms, obtaining test samples and tensile strength testing was based on the rules NTC5300, NTC5525, NSR10 and ISO / TC 165N315, and the cutting of culms protocols, test sample and determination of the tensión parallel to the fibers strength of the Universidad Nacional de Colombia in Bogotá. 120 tests were performed at the Universidad Nacional de Colombia in Bogoti The average valué of the parallel tensión strength was 61.0 MPa. Multivariate analysis of the experimental design, helped to identify the statistical significance of the section factors and area on the resistance to tensión with a p-value less than 0.05 and a confidence level of 95%, the second-order interaction was not significan t.
