| Abstract | The behavior of the elastic beam is discussed considering the in fluence of shear deformation. The Navier-Bernoulli hypothesis assumes that plane sections normal to the neutral axis before bending remain plane after deformation and normal to the neutral axis. Timoshenko beam theory is based on the assumption that plane sections normal to the neutral axis before bending remain plane after deformation but no longer normal to the neutral axis. In this study, a modification of the elementary beam theory is pro posed, taking into consideration the effect of shear deformation. Us ~. ing iterative technique, the solutions of the elementary beam theory and the Timoshenko beam theory are iterated successively for the discontinuity of longitudinal displacements arising as a result of shear deformation. Several numerical examples for beams with box section under simple loading cases and boundary conditions are given. For certain range of the parameters, fairly good agreement exists between the results of the proposed theory and those obtained by the more exact folded plate theory. |
