针对1艘钢管桁架式连接桥结构的小型双体船，采用直接计算法对连接桥进行局部强度评估。重点关注横向载荷，利用三维线性势流理论和设计波法计算双体船的波浪载荷，计算连接桥结构在危险工况下的结构响应，对不满足规范要求的杆件进行优化。结果表明，基于桁架式设计理念的连接桥强度满足要求，可为类似船型设计提供参考。
For a small catamaran with steel pipe truss bridge structure, the local strength of the connecting bridge is evaluated by direct calculation method. The transverse load is paid attention to, the wave load of catamaran is calculated by using three-dimensional linear potential flow theory and design wave method, the structural response of connecting bridge structure under dangerous working conditions is calculated, and the members that do not meet the requirements of the code are optimized. The results show that the strength of the bridge based on truss design concept meets the requirements and can be used as a reference for similar ship design.
