The ultimate bending moment and maximal shear stress of a bulk carrier with two structural forms (single hull and double hull/ are calculated separately by using the combined moment which is determined by stochastic process. Then the assessment of reliability is carried out. The results indicate that by introducing the double-hull structure, the shear stress of side can be decreased to half of that of the primary structure( 50.7% i. but the effect on longitudinal strength is not obvious. Finally, the effects of different double-side skin widths on ultimate bending moment and the maximal shear stress are investigated, followed by proposals of the selection of the double-side skin width. 相似文献

对于美国安全专家来说。每年将1100多万个集装箱运送到美国的巨大集装箱货轮就是潜在的特洛伊木马——每个都可能藏有大规模杀伤性武器。例如脏弹一但是通常情况下。只有靠岸并卸下所有的货物后.这些货轮才会被抽检并进行放射性检查,[第一段] 相似文献
