摘要: 基于现行混凝土结构加固设计规范关于粘贴纤维增强复合材料加固法的计算理论,分别对玄武岩纤维布和碳纤维布加固钢筋混凝土梁的正截面受弯承载力、斜截面受剪承载力进行计算分析,以探讨玄武岩纤维布对钢筋混凝土梁的加固效果。计算结果表明,设计人员可以方便地按现行加固设计规范对玄武岩纤维受弯、受剪加固进行计算。Abstract: Based on the design code for strengthening concrete structure,using the theory of calculating the flexural capacity and the shear capacity of RC beams with rectangular section strengthened by FRP,it is calculated and analysed the flexural capacity and the shear capacity of RC beams strengthened by BFRP sheets or CFRP sheets.The calculation process indicate that it is easy to calculate the flexural capacity and the shear capacity of RC beams strengthened by BFRP based on the design code for strengthening concrete structure.
