两铰拱的弹塑性分析

Plastonelastie Analysis of A Two Hinges Arch

通过对理想弹塑材料制成的对称两铰圆拱的讨论,确定在顶点集中载荷作用下,拱内产生的弯矩和顶点挠度,最后得出确定拱的承载能力的一般原则。

Through discussing the two hinges symmetric arch made the of ideal plastonelastic material,determinates the bending moment in the arch and the deflection of the apex,when concentrated load acts on the apex. In the end,obtains the general principle about determinating the bearing capacity of the arch.
