Abstract

In the numerical modeling presented, the deep beam is accounted for by means of a three dimensional FEA ANSYS 13.0 approach, in which the structure is modeled with load-displacement-based solid finite elements, whereas the internal work structure interacted by high strength concrete and reinforcement in full scale. Most deep beam collapse is dominated by the shear brittle collapse. Recently, confinement is the most effective way to improve the ductility of the reinforced concrete, whereas required to anticipate the occurrence of direct crack on the beam caused by quite large shear forces. Numerical models of deep beam with high strength concrete is done gradually by giving a variation of concrete strength, confinement and stirrup spacing. The two point load are applied with the ultimate load on all models. Then, analyzing of the deep beam is to be done with and without side reinforcement and also an analysis of the crack pattern of the beam to calculate the brittle area under the ratio of crack volume occurred. Concrete is modeled by SOLID65 and steel reinforcement using SOLID45 element. The collapses occurred are all ultimate flexural compressive collapse on the loading plate area, due to brittle shear collapse. The condition occurred on deep beam first crack was already considered a collapse, the density of reinforcement and the additional distance comprehensive reinforcement bar is most effective in terms of adding high ductility of high strength concrete beams. By using the stirrup reinforcement with confinement mode can significantly enhance the resistance of ultimate capacity, cracking ratio and reduced deflection.
