摘要
以统一的方式分析了轴压加筋板壳的弯扭稳定性.根据小挠度能量法,采用了约束剪心概念并考虑了加筋条偏心距,截面的翘曲刚度及剪心和形心间位置偏差等因素的影响,推导了屈曲方程。例题计算的结果表明了所提出方法的可行性。
The torsional-flexural sability analysis of stiffened panels and shells under axial compression is analysed in an unified way. Based on the small deflection energy methods the buckling equations are derived. In the derivation, the restrained shear centre concept is used, and the effects of the eccentricity of stiffeners, the warping rigidity and the position deviation between shear and mass centres of sections are included in considerations. The applicability of the presented method on practice is demonstrated by examples,
