| 摘 要： | 在国内外关于FRP(纤维增强复合材料)约束圆形混凝土柱的研究基础上，对FRP约束中必须考虑的相关参数即侧向约束刚度、约束强度、未约束混凝土的峰值应变、软化段界定等作了分析。提出新的三折线简化模型，并考虑到了上述参数的影响。与试验数据进行比较分析，结果表明该模型与试验数据吻合较好，该模型结构形式简单，参数取值方便。 |

| Abstract: | Based on the researches conducted by many scholars concerning the circular concrete column confined by FRP, many parameters related with FRP confinement including lateral confining stiffness, confining strength, unconfined concrete's maximum strain, transition determination etc. are analyzed. Simple three-straight-line model considering the above parameters is presented. The model, which has simple formulation and easier data available, has a good agreement with the test data indicates well agreement. |
| Keywords: | FRP concrete column stress-strain |
