In this paper, material non-linear analysis considering tensile fracture was developed from the viewpoint of hybrid displacement model. In this model, the concept of the spring of RBSM was introduced in Lagragian multiplier. In addition, compatibility of the displacement on the intersection boundary was approximately introduced using the penalty as a spring constant. First, the equivalent solution with the analytical solution was obtained when it examined the accuracy of elasticity solution using this model. As a result of comparison with the FE analysis, this model had the accuracy equal to constant strain element of finite element method. Next, as a result of the slip analysis, the slip lines and the collapse load were equal to RBSM. Finally, the equivalent tensile collapsing load with FEM was obtained when it carried out analysis of the bending problem for the plain concrete beam.
