Studies of contact problem have been widely executed by researchers with variable scopes, methods and definitions. A common problem occurs while handling contact phenomena is sliding through element boundary, discussed by Chen and Nakamura (1998), due to the discontinuity of the local coordinate between elements and a contact point. The common problem that occurs at an element boundary is a stable convergence result is hard to achieved, thus inspires authors to make a comparison of two different beam methods which are Euler-Bernoulli Beam Theory and Timoshenko Beam Theory for frictionless contact problem. Authors have been investigated geometrical non-linear analysis with extremely large displacements by using Tangent Stiffness Method, a robust non linear analysis method to execute analysis and produce results with high accuracy. In this study, a simple yet effective approach of a basic node to element contact phenomenon have been studied, which introduces a contact element consisted by three nodes. In this study, authors propose the modification of the beam elements with three nodes by considering the adaptation of shear deformation by TBT. The modification enables the contact point to slide through the element edge smoothly and some numerical examples are showed in this study
