摘　　要：提出了考虑剪切变形时变截面梁弯曲和稳定计算的传递矩阵法．利用解析法导出了等截面梁单元弯曲和稳定的正确传递矩阵，将变截面梁划分成一系列等截面梁单元，应用传递矩阵原理得到变截面梁弯曲和稳定计算的整体传递矩阵．最后。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.
