摘要
分析了 1 2片粘贴泰扶高强复合纤维的钢筋混凝土矩形梁的抗剪性能 ,并与 2片比较梁进行比较 ,研究该加固技术的抗剪加固效果。确定了纤维粘贴量、包裹方法和剪跨比等因素对钢筋混凝土加固梁抗剪性能的影响程度 ,提出了抗剪加固设计中的复合纤维设计应变的合理取值、加固设计模型和设计方法。通过非线性计算程序计算验证本文计算公式是合理的。
Shear property of 12 strengthened reinforced concrete beams is analyzed and compared with two RC beams. The resistant effects of shear and strengthening design method are studied on strengthened beams with advanced glass-fiber composites. Effects varying with different glass-fiber sticking ratios and different strengthening methods are determined from experimental data. The model and formula for calculating the shear capacity and important factors in the strengthening design are put forward. Results of the finite element method (FEM) analysis are in agreement with experimental data.
