In this paper, a simplified deformation analysis methodology for the three-dimensional body in the first order analysis (FOA) is proposed. A simplified finite element is developed for the tension and compression, and bending deformation as well as torsion deformation of the body by extending concept of beam element. The simplified finite element analysis via the developed element can estimate approximate deformations of complicate 3D-body, and the results of the analysis are useful for considering the load transmitting path of the structure and for designing the better layout of structure by changing the stiffness of structural components. We have improved the proposed method to reduce the simulation error because of the influence of the Poisson's ratio and the bending deformation. The validity of proposed method is examined through numerical examples.
