摘要
应用弹塑性稳定理论分析了桅杆起重机吊耳梁设计时应考虑的因素，得出方便实用的计算公式。此公式亦适用于其他狭长矩形截面悬臂结构的稳定性校核。
Based on elasto plastic stability theory,factors to be considered in designing beam with lifting eyes of a derrick crane are analysed and a simple convenient calculation formula is given This formula is also applicable checking stability of boom structure with other narrow rectangular sections It answers questions which can not be ignored,but are not covered by existing design regulation
