The two kinds of nonlinear buckling (primary buckling and secondarybifurcation 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;

For a secondarybifurcation 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.
