本文提出用观察法判定极限荷载下连续梁最后塑性铰的方法,可以使其极限位移的计算,绝大多数能够避免试算法的繁琐步骤。
This paper proposes an observation method to determine the final plastic hinge of a continuous beam under a limit load, which can be used to calculate the ultimate displacement. Most of them can avoid the tedious steps of the trial algorithm.
