It is an inelastic analysis during the linear monotony loads . it can show the actual yield mechanism and the appearance sequence of the hinge , find out the weakness of the structure and gain the pushover figure ( floor - shear diagram and element - shear diagram ) 进而揭示出在罕遇地震作用下结构实际的屈服机制，各塑性铰的出现顺序，找出结构的薄弱环节，确认结构设计中“强柱弱梁”的设计原则，得出push - over图形(层剪力图形及构件剪力图形) 。

Abstract : it presents the law of “ the reverse is positive ” on how to evaluate the unknown force of statically determinate structure , the movement law of force vector for drawing the axial force diagram and shear diagram . and expounds the simple and convenient method of drawing the moment diagram according to the rubber band deformation , and the auxiliary teaching software corresponding to the above - mentioned methods . the methods are believed to save class hour and gain a better effect on teaching 文摘:阐述了求静定结构未知力的反为正规律；绘制轴力图、剪力图的力矢移动法则；按照橡皮筋变形绘弯矩图的简便作法以及与上述方法对应的计算机辅助教学软件.相信这样作，对教学可起到省课时、效果好的作用
