拉线式桅杆的跨间稳定验算

Calculation of span stability of stay mast

鉴于拉线式桅杆的整体稳定计算尚停留在杆身分肢屈曲计算阶段,通过工程计算实例,介绍桅杆跨间稳定性的几种验算方法,并提出克服单肢变形,保证结构整体稳定性的措施,以供工程设计和检测核算参考。

Considering that the calculation of the overall stability of the stay wire mast is still in the stage of the buckling calculation of the members of the mast,this paper has passed the engineering.This paper introduces several checking methods for the stability of the span of a mast,and puts forward a method to overcome the deformation of a single leg and ensure the overall stability of the structure.For engineering design and test accounting reference.
