| 摘 要： | 基于大挠度理论给出一个含初始挠度、焊接残余应力缺陷加筋板格在横向载荷作用下有效带板宽度的计算公式,分析缺陷加筋板格的极限强度。并对 Faulkner型焊接残余应力板在均布载荷作用下进行了实际数值算例,分析表明上述诸因素均对极限强度有一定影响,这与实际情况是相符的。

| Abstract: | In this paper, analytical solutions for calculating the effective width of stiffened panel plating considering all the influences of initial deflection, residual stresses, transversely applied stresses and lateral loads are derived based on the elastic large deflection theory. The residual stress distribution adopts the Faulkner model. The uniform lateral loads have been considered. Numerical examples are given and the results indicate that all these factors have some effection on the effective width. Therefore, the present solutions provide a more accurate method for calculating the effective width of stiffened panel plating. |
