Abstract :There is no exactly analytical solution for the large deflection problem of prismatic cantilever beams under general loading conditions. In the case of considering a non-prismatic cantilever beam, the difficulty of the larger deflection problem is increased. In this study, the comparison of the Iterative Differential Quadrature Method insert ignore into journalissuearticles values(I-DQM); and the Combining Method insert ignore into journalissuearticles values(CM); was performed. Numerical solution of the large deflection problem was separately performed with both the I-DQM and the CM for prismatic cantilever beams. The obtaining results show that both of these methods gave more accurate solutions compared with a reliable semi-analytic method which was introduced by Dado and Sadder insert ignore into journalissuearticles values(2005);. Besides, it was demonstrated that the I-DQM provided a more wide-range solution than the CM.
