摘　　要：由于层压板梁的各向异性,载荷下结构响应和刚度特性难以确定。为了解决有限元方法在进行复合层压板梁的结构分析时参数确定的难题,提出了一种层压板工字梁的应力分析方法,并在MATLAB上编程实现,通过与理论计算值和有限元软件ANSYS分析结果进行对比,证明该方法可行,且适合于进行参数化研究设计。The anisotropic nature of composite materials makes it difficult to predict the structural respond and stiffness behavior under loading. The FEM technique can help structural engineers conduct the analysis and design. However, the process needs some certain parameters. The paper develops a simple method about the stress analysis of composite laminated beams with I- section by using MATLAB. By comparing with the results of theoretical method and FEM method, it is proved that the method is capable. Moreover, the method is suitable to conduct parametric studies about the composite laminated I-beam.
