| 摘 要： | 在试验的基础上,对高温下钢筋混凝土异形柱框架破坏形态进行了研究,考察了框架在梁、柱破坏形态下的结构变形及内力变化特征.结果显示梁破坏形态具有延性特征,柱破坏形态具有脆性破坏特征.在设计过程中要极力避免柱破坏形态的出现.

| Abstract: | Two failure mode, beam failure mode and column failure mode, of RC frame with specially-shaped column at elevated temperature, are studied in the paper at the basis of test. The paper presents the structure characteristic of the deformation and inner force of the two types of failure mode. Beam failure mode has the feature of ductility deformation, while column failure mode has brittle feature, which should be avoided in structure design. |

| Keywords: | Reinforce concrete specially-shaped column frame failure mode |
