Resumen


El presente estudio realiza un análisis comparativo del comportamiento estructural de conexiones empernadas madera-acero en configuración de doble cortante, evaluadas conforme a los lineamientos del Eurocódigo 5 (EN 1995-1-1:2022). Se aplicó un diseño experimental factorial y un análisis paramétrico mediante hojas de cálculo programadas, considerando las variables más influyentes en la capacidad portante: tipo de conector, clase resistente de la madera, clase de servicio, ángulo de carga, espesor de la placa de acero y número de pernos. Los resultados demuestran que los pernos de diámetros intermedios (M7–M10) alcanzan el mejor equilibrio entre eficiencia estructural y constructiva. Las condiciones ambientales adversas (clase de servicio 3) y la orientación diagonal de la carga (45°) generan reducciones superiores al 75% en la capacidad portante. Este estudio ofrece lineamientos técnicos para el diseño optimizado de conexiones híbridas madera-acero con base en principios normativos y comportamiento estructural real.
