The behavior of reinforced concrete beams can be determined by the analysis of calculation and FEM that beams with tensile collapsed condition has a lower flexural capacity and collapse behavior is more ductile than that of the beam with the compressive collapse and balanced condition. The results show that the reinforced concrete beams can be analyzed using ANSYS software with modified model.
The beams is subjected to concentrated load at middle span and collapsed behavior observed from load of the first crack up to fully collapse. The RC beam specimens of normal strength is modeled by rectangular section with tensile steel reinforcement ratios to represent the tensile, balanced, and compressive collapsed mechanism. The capacity of the bending moment, deformation, stress, strain and fracture patterns is determined that occurs on a single reinforced concrete beams with different types of collapsed mechanisms. This paper discusses about 3D ANSYS FE modeling of the failure behavior of structural reinforced concrete beam element.
