Evaluación de conexiones clavadas y atornilladas madera a madera de la especie cedrelinga cateniformis ducke sometidas a carga lateral según las normas awc/nds 2018 y nsr-10

Abstract

Wood is one of the oldest structural materials used by humankind and, in recent decades, has regained relevance due to its low environmental impact, carbon storage capacity, and mechanical efficiency compared to other building materials. in latin america, and especially in tropical countries, the availability of timber species with structural potential presents an opportunity to develop sustainable construction models adapted to local conditions. however, the structural use of tropical woods faces a technical challenge: most structural design and calculation standards, such as nds-24 (national design specification for wood construction) and nsr-18 (colombian seismic-resistant standard), have been developed based on species from temperate zones, with different physical and mechanical properties. this limits the direct application of design factors and performance models to tropical species such as cedrelinga cateniformis (achapo), whose industrial use has increased in the amazon region and in the wood processing clusters of bogotá, cundinamarca. the purpose of this work is to evaluate the structural behavior of joints in achapo wood through a comparative analysis of experimental results obtained in the laboratory and theoretical values calculated according to nds-24 and nsr-18 standards. to this end, test specimens assembled with nail and screw connectors were designed and tested, determining their yield strengths, elastic limits, and structural efficiency factors. this study provides technical evidence on the performance of a tropical species that is poorly documented in the structural literature, contributing to the understanding of the adaptability of international standards to the tropical context, and strengthening the foundations for a sustainable and technologically competitive timber industry in Colombia
