邮船餐厅顶部大空间结构立柱设计敏感性分析

为提高邮船空间感，减少大空间结构立柱数量，对某邮船项目餐厅顶部大空间结构进行剖析。对比规范计算、力学计算、梁系有限元计算、板梁结构有限元计算，分析有无立柱对分段质量、结构尺寸、净空高度、结构变形等方面的影响，分析大空间结构立柱设计敏感性，为邮船大空间结构立柱设计提供参考。

Sensitivity Analysis of Column Design for Large Space Structure on Top of Restaurant in Cruise Ship

In order to improve the space sense of cruise ship and reduce the column number of large space structure, the large space structure on top of restaurant in a cruise ship project is dissected. The standard calculation, mechanical calculation, beam system finite element calculation, and plate-girder structure finite element calculation are compared, the influence of whether there are columns on the section weight, structural size, headroom height, and structural deformation is analyzed, and the sensitivity of column design for large space structure is analyzed, which can provide reference for the column design for large space structure in cruise ship.
