By the calculation of castellated three hinge arch used in the Changchun Skating Gym, the several calculating method of castellated beam-columns are introduced in this paper.
本文就长春滑冰馆的蜂窝形空腹三铰拱的计算，探讨蜂窝形空腹压弯杆件的几种计算方法。
The in-plane stability formula of the lattice beam-columns derived from the edge yield criteria also applies to the castellated beam-columns, and the results are conservative.
由边缘屈服准则导出的格构式压弯构件平面内稳定计算公式，同样适合蜂窝式压弯构件弯矩作用平面内稳定计算，且结果偏于安全。
