摘要
对拱坝的弹塑性应力分析,目前尚不多见。本文在多拱梁位移法的基础上,用初内力的方法,对拱坝作杆系结构的弹塑性应力分析,避开了求弹塑性单刚,使计算工作量大为减少,为拱坝弹塑性应力分析提供了工具。
The writer uses the method of initial force to carry on plasticityeiasticity analysis for bar System. With this method generating plasticityelasticity element stiffness matrix can be avoied so that the work of calculation can be reduced, a great deal. This method can be used as an efficient tool for analizing the plasticity-elasticity of arch dams.
