为了研究强梁腹板连续开孔对大跨度板架静力和动力特性的影响，以某大型客滚船为例，分别分析连续开孔对大跨度板架总强度、局部强度及固有特性的影响，并讨论了连续开孔在总强度、局部强度及固有特性分析中的模拟方法。同时，通过对比分析得出腹板开孔引起的应力集中系数以及开孔注意事项，为大跨度板架结构的设计提供参考和依据。
In order to study the influence of continuous openings in web frame on static and dynamic characteristics of long-span plate frames. Tanking a Ropax ship as an example, the effects of continuous openings on ship hull strength, local strength and natural characteristics of long-span plate frames are analyzed respectively. The simulation method of continuous openings in the analysis of ship hull strength, local strength and natural characteristics is discussed. At the same time the stress concentration factor caused by opening and precautions are obtained through comparative analysis. It provides reference for design of long-span plate frame structure.
