摘要
对 12根GFRP加固的钢筋混凝土梁的试验结果进行了抗弯承载力分析 ,并在此基础上对影响抗弯承载力的因素进行了分析。分析结果表明 ,FRP加固量、弹性模量、抗拉强度、钢筋屈服强度、配筋率及梁底初始拉应变对抗弯承载力有明显影响 ,而混凝土强度对抗弯承载力的影响并不显著。
The analyses of bending load capacity of the test results of 12 RC beams strengthened with glass fiber reinforced plastic(GFRP)plates were conducted and on the basis of which the factors influencing the bending load capacity were also analyzed.The results showed that GFRP strengthening,modulus of elasticity,tensile strength,yield strength of rebar,steel ratio and the initial tensile strain at beam bottom have obvious effects on the bending load capacity;whereas the effect of the concrete strength is not evident.
