摘要
传统的求单层板架临界应力的方法只能处理一些对称形式的板架，用有限元法克服了这一局限，可以求解任意形式平面单层板架的临界应力算例的比较和分析表明这种做法是合理可行的以此为基础，按Ｒｏｓｅｎｂｌｕｅｔｈ法进一步计算了船体极限弯矩的统计值。
The traditional method for calculating the critical stress of the grillage is not well adaptable.The paper employs the finite element method to solve this problem.With a large number of numerical examples ,the correctness of the calculating program is proved.Then the Rosenblueth method is used to calculate the statistical characteristic values of the ultimate bending moment of the ship-hull which has single-hull deck.Moreover,the effect of the individual and joint variance of the basic random variables on the statistical characteristic values is discussed.
