| Abstract | This study presents a new method of finite analysis modeling of a reinforced concrete beam-column finite element analysis which obviously considers for shear and the bond slip between the steel bars and over surrounding concrete and also the anchorage slip between them. The element formulation incorporates the sectional fiber model with a traditional finite element model in which the section is assumed to be plain while the strains of the bars are computed as the both total of the internal rebar deformations and the anchorage slip. This initial modeling technique is applied to a rectangular cross section under uniaxial bending and cyclic loading. The basic element algorithm is to formulate the shear mechanism at each concrete fiber of the cross section. Therefore, the resulting of proposed model with integral method, although numerically more intensive than the traditional fiber element determination, results in a better agreement to the experimentally determined hysteretic behavior. It is noticed from the comparisons of results that the effects of bond, slip and shear on an element with consideration of anchorage slip is essential to be predictable the behavior of a reinforced concrete beam section in these considered mechanisms. |
