基于双剪屈服准则钢筋混凝土轴对称圆球壳有矩理论的极限分析

摘要

The plasticity yield condition of the reinforced concrete axisymmetric spherical shell with moment theory based on the twin shear stress yield criterion has been derived. Applied the plastic theory, the limitation analysis of the spherical shell have been studied. Then the limitary loads of the shell under the equal load using kinematics analysis method have been calculated. The calculation results are consistent with the result using the plastics yield line theory. The results can be used for providing a theoretical method for executive departments.%基于双剪屈服准则,导出了钢筋混凝土轴对称圆球壳的有矩理论的屈服条件,并应用塑性理论,对钢筋混凝土圆球壳进行了极限分析,并用机动法求出壳体在竖向均布荷载下的极限载荷.计算结果与根据塑性屈服线理论计算的结果相符,可供工程技术部门参考.
