摘　　要：客船因其结构的特殊性,拥有数量庞大的立柱,且存在上下非对齐立柱,目前规范中没有针对客船立柱的强度评估指南。以一双体客船的整船立柱为研究对象,利用有限元方法,开展整船载荷下和局部载荷下的立柱强度计算,充分对比两种计算下立柱的屈服和屈曲强度。结果表明:对于双体客船,影响立柱结构强度的主导因素是局部载荷,非对齐立柱会导致横梁和纵桁应力集中,设计中需重点关注。A passenger ship has a large number of pillars due to its special structure,and there are non-aligned pillars vertically.In current specifications there is no strength assessment guideline for the pillars of a passenger ship.Taking the whole ship pillars of a catamaran passenger ship as a research object,the finite element method is utilized to carry out the strength calculation of pillars under the whole ship integral load and local loads respectively,and the yield and buckling strengths of the pillars under the two kinds of calculation are fully compared,and the results show that:for a catamaran passenger ship,the dominant factor for the strength of the pillar structure is local load,and the non-aligned pillars lead to the stress concentration of the transverse beams and longitudinal girders,which need to be particularly focused in the design.
