Numerical Investigation of Reinforced Concrete Beam Due to Shear Failure

This paper investigates the possibility of using a multi-surface plasticity model to predict shear failure in reinforced concrete beams. The analysis is carried out in-house software called 3D-NLFEA. constitutive for material based on plasticity-fracture model, which had previously developed simulate behavior cover spalling columns. To obtain asymmetric pattern, random properties imperfection each meshed element used. Two beams available literature are investigated and compared with results From comparisons, excellent agreement between test result was obtained. 3D-NLFEA can peak load accurately. prediction only varies 2.19% beam OA1 3.28 % OA2, it lower than results. crack patterns also show typical diagonal extension from support loading steel plate.
