| Abstract: | The transfer matrix method for the bending and stability of the variable section beams with shear deformation is presented. By use of analytical method the exact transfer matrices of the bending and stability of the beam element with uniform section are derived. Then, the variable section beams are devided into a series of beam elements with uniform section and the globle transfer matrix of the bending and stability calculation of the variable section beams is obtained by applying the principle of transfer matrix method. Finally,some numerical calculation results are given. |
