摘要
本文对弹性扁圆拱在拱顶受集中载荷作用时的大变形进行了非线性分析，得出了不同支承条件下拱的大变形封闭解，给出拱的变形特性和屈曲载荷，并提出了临界拱顶住移的概念。
his paper analyses the large deflection of elastic circular arches subjected to a concentratedforce at the arch-top.The closed solutions of nonlinear deformation and the buckling loads ofshallowed arches for different supported conditions are obtained.And the conception of critical arch-top deflection is presented.
