本文指出了在设计承受横向和轴向荷载的压弯格构式铁塔柱子时,往往忽略因柱子挠曲而由轴向力产生的附加剪力,而这种忽略有时会引起柱子强度的不足以导致铁塔损坏。本文对这种计算方法提出了建议公式并附有计算实例,对我国钢结构设计规范中有关这方面的规定也作了分析探讨。本文可以作为铁塔设计和制定有关设计技术规定时参考。 This paper points out that when designing bent column grid columns that are subjected to transverse and axial loads, the additional shear force due to column deflection due to axial forces is often neglected. This neglect sometimes results in insufficient column strength. Caused damage to the tower. In this paper, the proposed formula is put forward and the calculation example is attached to this calculation method. The regulations on steel structure design specification in this respect are also analyzed and discussed. This article can be used as a reference for designing and formulating design specifications for iron towers.
