截面应力内力相互转化的初步研究

Elementary Study of Conversion Between Section Internal Force and Stress

渡槽等水工建筑物的三维有限元力学分析结果为应力形式,不能直接用来进行配筋设计,研究应力内力相互转化的方法,通过对梁的边界条件、应力特点的研究,得出了适用于一般情况的转化公式,编制了转化程序,经典题目和工程实例验证了方法的可行性。

Three-dimensional finite element mechanical analysis result of hydraulic building such as flume is stress format,which can not be used to design for reinforcement. The paper put forward the opinion of conversion between internal force and stress. By the study of boundary condition and stress,get the conversion formula which suit for general case and compile the conversion program. Classical subject and engineering case have proved the feasibility.
