摘要
文章利用基于双剪屈服线准则所导出的钢筋砼壳体的屈服条件,并利用塑性屈服线方法求解钢筋砼轴对称双曲扁壳在竖向荷载下的极限载荷。
This paper presents the yield conditions of the reinforced concrete spherical shell based on twin shear yield criterion, and determinates the limite load of a simply supported spherical shallow shell by using the theory of the plastic yield lines.
