摘要
对14根钢筋混凝土矩形梁进行抗剪加固试验,研究在受剪区粘贴高强复合纤维的加固效果和设计方法。主要分析了纤维粘贴量、包裹方法和剪跨比等因素对钢筋混凝土加固梁受剪性能的影响和作用。对试验梁进行了全过程分析,并基于试验结果,提出了抗剪加固设计中复合纤维设计应变的合理取值和计算公式,阐述了具体加固设计模型和设计方法。
Based on the resistant to shearing of fourteen reinforced concrete beams ,the effectives of the shear property and designing method of strengthening are studied for the RC beams strengthened with advanced glass-fiber composites .The paper analyzes and discusses the effects varying with different glass-fiber sticking ratios and different strengthening methods. The whole process of the experimental beams are analyzed. The model and formula for calculating the shear capacity and important factors in the strengthening design are put forward on the basis of the experimental results.
