摘　　要：客滚船的上层建筑为抵抗由于不对称风浪和惯性载荷而产生较大的横向弯矩,往往采用横向半舱壁结构形式以解决横向挠曲强度和变形问题,目前中国船级社对上层建筑横向半舱壁结构的强度未明确校核方法和适用衡准,故采用全船有限元计算方法和挪威船级社软件PULS,对横向半舱壁结构进行强度校核,并根据计算结果结合功能需求,提出提高客滚船横向半舱壁结构强度的措施。In order to resist the large transverse bending moment caused by asymmetric wind and inertia load,the transverse semi-bulkhead structures are adopts in the superstructures on Ro-Ro-passenger ships to optimize the racking strength and deformation.At present,the analytical method and applicable criteria for strength of the transverse semi-bulkhead structure are not specified in CCS rules.A method was put forward to assess the racking strength of this kind of structure by combining finite element analysis of whole ship structure and application of DNV PULS software.The measures to improve the strength of the transverse semi-bulkhead structures were introduced according to the calculation results taking the requirements for functional arrangement into consideration.
