| 摘 要： | 在大量检测验证的基础上,得到了结构加固用碳纤维布力学指标的统计参数,基于结构可靠度理论方法,通过钢筋混凝土梁采用碳纤维布加固前后的可靠指标计算比较分析,研究了碳纤维布加固钢筋混凝土梁的可靠度水平的变化。同时讨论了各随机变量均值及变异系数对碳纤维布加固混凝土梁可靠指标的影响趋势及程度,为碳纤维布加固混凝土受弯构件的应用范围提供了基础判据,按照这个思路,可以对不同类型FRP材料加固不同构件的可靠度进行分析。

| Abstract: | Mechanical statistical parameters of carbon fiber sheets for structure reinforced are acquired on the basis of abundant surveys and validations.The reliability index before and after reinforcement concrete beams strengthened with carbon fiber sheets is studied.Influences of random variables and their coefficient values to reliability parameters are discussed,which lays foundation for application of RC flexural members strengthened with carbon fiber sheets.Similarly,reliability analysis of different members reinforced by different FRP materials could be done to guide the engineering application of FRP reinforced concrete structures. |
