摘要
外粘钢板等加固混凝土梁技术是目前较为流行的结构加固方法。为了比较不同的粘贴材料对结构承载力的影响,使用钢板、环氧树脂板、玻璃丝布等 3种不同的粘贴材料对承载力损失后的构件进行加固,通过试验的方法确定其加固效果。试验结果表明,各种加固材料基本满足了承载力的加固要求,加固后的承载力比原构件都有不同程度的提高但使用钢板和环氧树脂提高幅度更大。
The technique of reinforcing concrete beam by cementing steel plate is a popular method for structure reinforcement. In order to compare the effects of different cemented material on the carrying capacity of structure, the paper selects three different cemented materials of steel plate, epoxy resin plate and glass fibre fabric to test the component that has lost carrying capacity. The outcome shows that all the materials for reinforcement have basically meet the requirements, the carrying capacity after reinforcement all has been increased to different levels comparing with original component and the incremental range of the capacity of steel plate and epoxy resin plate is greater than that of glass fibre fabric.
