摘　　要：根据双重迭加方法所导出的位移场模型以及相应的位移形式的平衡方程 ,对于简支层合梁受一般载荷作用下的问题 ,简化成求解其代数方程组的问题 .Based on double superposition hypothesis, the displacement field of the laminated beam is established, which has fixed unknowns and satisfied the stress and displacement continuity conditions at interfaces. For simply supported composite laminated beams under general load forms, the equilibrium equations are changed into the algebraic equations by using Fourier series, and then the analytic solutions are obtained. All of the results are compared with 3D elastic solutions. The results are fairly satisfactory.
