Structural engineers have long recognized the importance of member ductility,that is member rotation,in the design of reinforced concrete structures in order to redistribute moment and absorb energy due to dynamic,seismic,and blast loads.Understanding the rotation mechanism has been a difficult task due to the complex and variable behavior of reinforced concrete members and this is reflected in the slow but steady research progress.In this paper,the three components of the rotational mechanism of reinforced concrete beams are described.The rotation due to yield penetration of the reinforcing bars is then mathematically quantified using partial-interaction theory,which depends on the bond characteristics.The results are compared with published empirical approaches and shown to be in good agreement.Finally,a variable hinge length that is specific to the rotation limit due to fracture of the reinforcing bar,that is yield penetration,is mathematically developed.

结构工程师很早就认识到部件延展性, 即是 （member rotation, 具体学术名我不知道,大概是 “部件旋转力或扭力”）, 在钢筋混凝土结构中去重新分配受力时间和吸收动态,地震和爆炸载荷的重要性. 真正的理解回转原理是一项艰巨的任务主要因为钢筋混凝土的复杂和多变的行为特性, 而这种困难体现在对于它缓慢却稳步的研究进程. 在这篇论文中, 将对钢筋混凝土的回转原理的三个构成部分进行描述. 这种由于对钢筋穿透产生的回转将会用不完全相互作用理论来进行数学量化, 这个过程取决于成键特性.然后用得到的结果跟已发表的实践性方法所得到的结果进行比较. 最后, 一个由于钢筋断裂所产生的枢纽长度将会用数学方法建立起来.
