Numerical Modeling of Reinforced Concrete T-Beams

ATENA Engineering 3D software was used to build various numerical models of a RC specimen that was tested in the Laboratory of Heavy Structures of NOVA School of Science and Technology. Specimen CB0 was the reference one of a broader experimental campaign. The sensitivity analysis was carried out after the experimental campaign, aiming to understand better the influence of different factors, such as the FE type and size, and the fracture energy. The obtained results were compared with the experimental results of beam CB0. The behaviour of the numerical model built with 40 mm quadrilateral FE was found to be the most appropriate one.
