Secondary buckling mode of shallow arches depended on the ratio of rise to gyration radius.
对于矢跨比较小的坦拱，矢高与截面回转半径的比值将决定拱的屈曲形式。
For a secondary bifurcation buckling load, the limit load carried capacity of the arch of 0.1 rise-span ratio is the biggest one under a full span load distribution.
全跨均布荷载作用下，矢跨比0.1的拱极值点屈曲和二次分岔屈曲极限承载力均大于其他拱。
The two kinds of nonlinear buckling (primary buckling and secondary bifurcation buckling) of elastic arches are elaborated in detail.
本文详细阐述了拱的非线性屈曲的两种形式，即极值点屈曲和二次分叉屈曲；
