Simulation model to estimate bending overstrength in concrete elements

A simulation model to estimate bending overstrength in reinforced concrete elements is presented. The simulation model employs basic design hypotheses according to NTC–04 [1] and ACI 318–11 [2] for rectangular concrete beams subjected to bending with rebars in the tension zone only. Concrete compres...

The simulation model employs basic design hypotheses according to NTC–04 [1] and ACI 318–11 [2] for rectangular concrete beams subjected to bending with rebars in the tension zone only. Concrete compression strength is included in the model as a random variable to estimate the uncertainty in bending strength on rectangular beams.

El modelo de simulación emplea las hipótesis básicas de diseño de acuerdo con las NTC–04 [1], así como con el ACI 318–11 [2] para vigas de sección rectangular con acero de refuerzo solamente en la zona de tensión. La resistencia a la compresión del concreto se integra al modelo como una variable aleatoria con el fin de estimar la incertidumbre en la resistencia a flexión de las vigas. La resistencia a la compresión del concreto se estima a partir de más de 16 mil pruebas con mezclas diseñadas para obtener 200 kg/cm2 (19.6 MPa) y 250 kg/cm2 (24.5 MPa). El principal objetivo de este trabajo es el de evaluar la influencia que tiene la resistencia a la compresión del concreto en la sobrerresistencia estimada a flexión empleando modelos analíticos que se encuentran en los reglamentos de diseño como lo son las NTC–04 y el ACI 318–11.application/pdfspaUniversidad Nacional de Colombia (Sede Medellín).
