Estudio Probabilístico de Secciones Transversales Poligonales de Concreto Armado Sometidas a Flexo-Compresión Oblicua

Abstract

El objetivo de este trabajo es presentar un modelo probabilístico para el análisis de secciones rectangulares de hormigón armado sometidas a flexo-compresión oblicua en el estado límite último. Se emplea el diagrama parábola-rectángulo para el hormigón y un diagrama bilineal para el acero, transformando las integrales de superficie en integrales de línea. La configuración deformada que corresponde al equilibrio en la rotura se determina mediante el método de Newton-Raphson. Las principales propiedades mecánicas, geométricas y de carga se consideran variables aleatorias. Mediante el método FORM se obtiene la capacidad resistente de la sección y se estima el índice de confiabilidad. Finalmente, se presentan ábacos de diseño y de confiabilidad desarrollados de acuerdo con la norma brasileña NBR-6118/2023.
