The purpose of this paper is to propose a theory and method which will enable a ship designer to evaluate analytically the longitudinal bending,str- ess in long superstructure and main hull girder of a ship,respectively in bending and thus in turn the effectiveness of a long superstructure as a longitudinal strength member of a ship.Although in recent years,there is no lack of paper dealing with long superstructure,however,this is the first paper ever published,which has taken the actual loading conditions of a ship and also the effect of the presence of transverse bulkheads and webs under the deckhouse into consideration. Also as an illustration,the bending stress analysis for the passenger ship S.S.“President Wilson”made by this method shows the calculated results agree reasonably well with the test results.

In ship structure, the influence of nonuniform torsion upon the bending of angles or bulb angles with plating under lateral load may not be neglected.This paper presents an approximate method for calculating the strength of a beam with asymmetric section, in which the web is inclined with plating.The assumptions are cited: a) During nonuniform torsion, the web and the plating will be deformed.b) The position of shear center is in the plane of plating.The position of shear center, the warping function,...

In ship structure, the influence of nonuniform torsion upon the bending of angles or bulb angles with plating under lateral load may not be neglected.This paper presents an approximate method for calculating the strength of a beam with asymmetric section, in which the web is inclined with plating.The assumptions are cited: a) During nonuniform torsion, the web and the plating will be deformed.b) The position of shear center is in the plane of plating.The position of shear center, the warping function, the moment of inertia of flange and the approximate expression for the displacement of flange are obtained by using the theory of nonuniform torsion of thin-walled bars with open cross section.The flange is then treated as a beam on elastic foundation, which is formed by web and plating, and a differential equation of the flange is derived. This is obvious from the experimental results and the calculated values, in which the influence of nonuniforin torsion upon strength is significant and the increased stresses due to this influence are 30~120% of the simple bending stresses.The calculated values show close agreement with the test results. Finally, a suggestion for the structural type is made in this paper.

船舶结构中,弯扭变形对于承受横向荷重的非对称梁强度影响往往不能忽略。本文引用扭转时腹板与壳板产生弯曲变形以及弯心位于壳板平面内的假定,应用薄壁杆件理论求得剪心、扇性面积和翼板惯性矩,以及翼板位移的近似式,将翼板当作弹性基础梁,立出翼板的微分方程,推导出在横向荷重作用下腹板与平板斜交的非对称梁强度近似计算方法。从试验和计算的结果可见,弯扭变形对强度影响很大,由此变形所引起的附加应力约为一般弯曲应力的30~120%。计算结果与计算结果基本一致,表明计算方法基本可靠。最后对结构型式提出建议。
