Abstract
This project consists of making T-connections from Kunth guadua angustifolia joints, focusing the research on determining their behavior under tensile stresses, changing the injection with mortar as proposed by NSR-10-chapter G-12, for a mixture of RPET (recycled polyethylene terephthalate) and PS (polystyrene) plastic material. This study is proposed to the extent that guadua as an engineering material is used in different types of construction for homes, bridges, support structures, among others. However, in Colombia the available research and information about the admissible tensile strength offered by this element for structural purposes can be considered deficient compared to the benefits offered by said material. Therefore, an investigation is developed with a quantitative approach of an experimental type, in which a dosage of model mixtures for the injection polymeric matrix was carried out; specimens from the department of Norte de Santander were taken; and the tensile stress tests were carried out on the samples, for which acting tensile strengths (ft) between 1.74 MPa and 3.20 MPa were reached, which compared to the modified allowable tensile stress (F't) that under coefficients of Modification of load duration and temperature yielded a value of 16.20 MPa; which indicates a positive result given that the criterion that ft ? F't set forth in Regulation NSR-10, chapter G-12 Structures in Guadua is met.
