摘　　要：[目的]中央大厅是邮轮上层建筑中一种重要空间功能性舱室,其结构具有板厚薄、跨度大、支撑少、载荷复杂等特点,为结构设计带来了较大的难度。亟需提出一种可靠便捷的中央大厅结构分析评估方法,用以指导结构设计工作。[方法]以中国船级社(CCS)《邮轮局部结构直接计算指南2021》为主要依据,结合中央大厅结构载荷特点,开展邮轮中央大厅结构直接计算研究。直接计算研究中,结构所受载荷被等效并简化为总纵弯矩载荷、垂向剪切载荷、以及局部甲板载重的叠加。[结果]结构直接计算结果与全船有限元仿真结果吻合较好,验证了将直接计算流程应用于邮轮中央大厅结构设计研究的可行性。[结论]研究结果可为大型邮轮中央大厅结构设计计算流程提供参考。[Objectives]The atrium structure is an important functional cabin in the superstructure of a large cruise ship.Atriums have a large spatial span and are always subjected to complex loads.A fast and reliable safety assessment simulation method for atrium structures is required to assist in their structural design.[Methods]Based on the Guidance for Direct Calculation of Local Structures of Cruise Ships 2021 by the China Classification Society(CCS)and the loading characteristics of atriums,a direct calculation design method is proposed in which loads on structures are equivalent to combined simplified loads in three groups,namely longitudinal bending,vertical shear and local cargo pressure.[Results]The results of the proposed direct calculation design method of a specific atrium structure are in good agreement with the wholeship finite element analytical results,verifying its effectiveness.[Conclusions]This study can provide guidance for the design process of atrium structures in large cruise ships.
