Caracterización de las propiedades físico - mecánicas de la guadua angustifolia kunt proveniente de la ciudad de Villavicencio (Meta).

Abstract

Guadua angustifolia stands out as one of the top 20 bamboo species worldwide, thanks to its fast growth and high productivity. In addition to these properties, guadua angustifolia has favourable characteristics that make it highly valued in various applications, especially in sustainable construction and other industries due to its strength and versatility. Aim of this research is to determine the physical and mechanical characteristics of guadua angustifolia Kunt from Villavicencio (Meta) and its capacity to comply with the minimum parameters established in the Seismic Resistant Standard NSR-10, in order to determine its viability as an alternative structural material in housing construction, especially in the context of the growing housing deficit problem in Colombia, particularly in rural areas and low-income communities, where the lack of adequate housing is a persistent problem. To carry out this research, 8 guadua angustifolia Kunt canes were used, each one with a length of 7 meters, extracted from the Moniyamena farm in the Las Mercedes village, located at Km 14 of the road to Acacias in Villavicencio, Meta. These culms were divided into three sections: Cepa(lower), Basa(middle) and Sobrebasa(upper). Several tests were carried out, including axial compression, bending, shearing parallel to the fibers (with and without knots) and tension parallel to the fibers, using a total of 193 specimens to characterize the properties of the guadua. In addition to these tests, density and moisture content tests were carried out. It is important to note that the guadua culms were not subjected to any drying treatment and were submerged for at least 2 weeks, as established by the corresponding regulations.
