| 摘 要： | 以材料的力学性能分析为基础，利用双界限系数将碳纤维增强混凝土受弯构件划分成三种正截面的破坏形态，对每一种破坏形态，建立了单、双筋矩形截面极限承载力的计算式，使碳纤维增强混凝土构件正截面计算与现行的规范相一致。

| Abstract: | Based on the analyses of material mechanical property, the failure forms of the cross section of the bending concrete structure strengthened by carbon fiber are divided into three types by use of the double-critical factors method. The formulas for calculation of the ultimate bearing capacity of single and double reinforced rectangular cross sections for each failure form are set up. Consequently the design calculation of the cross section of the concrete structure strengthened by carbon fiber agrees well with the current code. |
