Descomposición Geométrico-Hiperestática y Análisis de la Fuerza de Hendimiento en Columnas Arbóreas de Hormigón Armado

Abstract

Se presenta una metodología numérica para el diseño morfológico de columnas arbóreas tridimensionales de concreto reforzado, basada en la minimización iterativa del residuo ortogonal de equilibrio mediante relajación angular dinámica sobre un modelo FEM Timoshenko 3D. El trabajo propone una unificación entre el form-finding funicular y la verificación nodal STM-MCFT mediante una descomposición ortogonal del residuo inducida por el jacobiano del operador de equilibrio, demostrando que en un punto estacionario del funcional objetivo la componente geométrica se anula y el residuo remanente es irreducible mediante ajustes angulares. Se incluye un estudio paramétrico sobre cinco combinaciones de carga gravitacional que demuestra la invariancia práctica de la geometría óptima ante variaciones de magnitud y distribución de carga.
