| Abstract | ||
| This paper describes a comparison between beam-column junctions with and without construction joint, also, a parametric study deals with construction joint is presented by taking various conditions of the junction. These include the various positions of the construction joint, the axial load on the column, strength of concrete in the second cast and the amount of dowels crossing the joint. By developing a computer program which was originally written by Dr. Ihsan Al-Shaarbaf (1990), (P3DNFEA, program of three dimensional nonlinear finite element analysis), to consider the effect of construction joint depending on the fact that the shear force can be transmitted across the shear plane either by interlocking of the aggregate particles protruding from each face or by dowel action of the reinforcement crossing the cracks by using Fronteddu’s and Millard’s models, respectively. It is concluded that the construction joints existed in the beam-column junctions result in a significant reduction in the in-plane shear stiffness and it would affect only on the rotation and shear strains of the joint. | ||
