| 摘 要： | 利用正则弯矩和正则曲率,提出了梁元失效包络图、工作状态图以及失效指标的概念.基于此,进一步提出了多跨梁的失效包络图、工作状态图及失效指标的概念,并定义了不同的失效指标.对一个三跨超静定连续梁进行了失效评估,提出了若干失效评估需进一步研究的课题.

| Abstract: | The failure envelope,the state diagram,and the failure index of beam elements are proposed using the normalized moment and the normalized curvature.Based on this,the failure envelope,the state diagram,and the failure index of multi-span beams are initiated.Structure assessment from various angels can be carried out with different failure indexes.The failure assessment of a three span statically indeterminate continuous beam is conducted,and some further issues of failure assessment are mentioned. |

| Keywords: | beam elements multi-span beams failure envelope failure index failure assessment |
