摘　　要：在考虑塑性的结构分析中,结构破坏标志是结构中出现了足够多的塑性铰,结构变成可变体系,从而破坏。因此,结构中出现的第一个塑性铰必须有足够的转动能力,以保证在继续加载后,其他截面也出现塑性铰。利用有限元法对钢筋混凝土连续梁的塑性铰转动能力进行计算,以确定结构出现的第一个塑性铰有足够的转动能力。In the Structural Plasticity Analysis,the symbol of structural fracture is that there are enough plastic hinges in the structure,the structure is geometrically unstable system and fracture.The first plastic hinge must have the ability of rotation to make sure that there are plastic hinges on the other sections under the load.The ability of rotation of plastic hinge in RC continuous beam with the finite element method to ensure that the ability of rotation of the first plastic hinge is enough.
