摘要:
采用泛函极值分析方法,推导出圆拱截面函数和挠曲函数的稳定方程.利用瑞利里兹法,近似求解在静水压力作用下,两铰圆拱呈反对称屈曲和正对称屈曲状态的临界荷载和截面的优化形式.
Abstract:
By adopting the method of functional extremum analysis, the author derives the stability equation for section function and flexure function of circular arch. By using Rayleigh-Ritz method, he solves approximately the optimized form of critical load and section of two-hinged circular arch in antisymmetrical buckling and symmetrical buckling state under the action of hydrostatic pressure.
