| 摘 要： | 对采用 FRP片材抗弯加固的钢筋混凝土梁 ,进行正截面弯矩 -曲率分析 ;对抗弯承载力参数进行分析 ,提出对加固梁抗弯承载力设计方法的建议 .分析结果表明 ,加固量、FRP片材的弹性模量和强度、混凝土强度 ,以及梁的配筋率对抗弯承载力有较大影响 .用 FRP片材对低配筋梁进行抗弯加固效果明显 ,但必须考虑抗弯加固所导致的脆性破坏 .

| Abstract: | The sheets of glass fibre reinforced plastics (GFRP) are adopted to resist bending of a RC beam and to strengthen it. The obvious effect of GFRP in resisting bending of the beam with low reinforcement ratio and in strengthening it is shown by the results of relevent analyses. These analyses include its front sectional moment curvatare analysis and parametric analysis of its bending resistance and bearing capacity. Moreover, some suggestions are made on the method of designing bending resistance and bearing capacity of strengthened beam. |
