Abstract

The behavior of compression resistance perpendicular to the fiber of guadua bamboo test pieces was evaluated through an analysis of multifactorial variance (ANOVA). The samples object of studies came from four areas located in the municipality of Pitalito to the south of Huila department. They were tested at the Institute of Extension and Research (IEI) of the National University of Colombia in Bogotá. The 112 samples tested with compression perpendicular to the fiber obtained an average moisture content in the samples of the SA Group of 98.86% and in the samples of the SB Group of 113.51%, with standard deviations of 14.98% and 27.21% respectively. The analysis of multifactorial variance of Guadua angustifolia in relation to 3 factors (Area, Guadua Section, Saturation) through an experimental design, allowed to identify that the 3 factors and their interactions of first and second order do not have significant effects on the resistance to perpendicular compression with a p-value higher than 0.05. The admissible effort to perpendicular compression was also found according to the procedure described in the Colombian Seismic-Resistant Standard (NSR-10), finding that for the SA Group's test pieces, this effort is of greater magnitude than the one described in the standard. Finally, the Circumferential Elasticity Moduli were found according to the procedure described by L.A. Torres & García, (2007).
