摘要
在起重船扒杆设计中，现行《船舶及海上设施起重设备规范》没有提供直接强度计算方法，容易导致强度计算缺乏统一标准和审图产生困难。作者认为，《钢结构设计规范》（GB50017）提供的有关计算会式可作为船舶工程中起重扒杆以及其它压弯构件的计算方法。
In the design for derrick mast of the hoisting vessel, in the current 《Rules for the Lifting Appliances on Ships and Offshore Installations Rules for the Lifting Appliances on Ships and Offshore Installations》 there is no guideline of direct strength calculation which will induce lack of unify standard for strength analysis and difficulty in plans examining. Author considers that the relative calculating formula provided in 《Code for Design of Steel Structures》 （GB50017） could be appied in derrick mast and other press bending member calculation in ship engineering.
