大型邮轮上层建筑舷侧开口结构剪切强度试验研究

Experimental Study on Shear Strength of Opening Structure at Side of Superstructure of Large Cruise Ship

以某大型邮轮上层建筑舷侧局部结构为研究对象,设计两种典型舷侧开口结构的缩比模型并开展了剪切强度试验研究,探究了在剪切载荷作用下大型邮轮舷侧局部开口结构的屈曲失效模式、应力状态和极限承载能力,归纳了舷侧开口结构的变形特点和应力分布特征。研究结果对于国内大型邮轮上层建筑舷侧结构设计及剪切强度评估具有较大参考价值。

Taking the side structure of the superstructure of a cruise ship as the research object,two typical scaled models of side opening structures are designed and their shear strength experiments are carried out.Buckling failure mode,stress state and ultimately carrying capability of the models are investigated under shear loads.Characteristics of deformation and stress distribution of the side structure with openings are summarized.Research findings have great reference value for the structural design and shear strength evaluation of cruise ships.
