混凝土结构是目前采用最广泛的结构形式,混凝土材料由于碳化、环境腐蚀、保护层脱落等问题,会导致结构承载力不足,影响继续使用.对结构进行加固维修使其满足结构的安全性、耐久性具有重要意义.纤维增强复合材料(FRP)加固土木工程结构是近年来国内外研究的热点,纤维增强复合材料具有轻质、高强、耐腐、便于施工等优点,在加固领域得到广泛应用.采用拉拔试验和梁式试验分析嵌入式FRP与混凝土的粘结性能,为FRP嵌入式加固混凝土结构提供参考.
The concrete structure is the most widely used structure. Due to carbonation of concrete, environmental corrosion, concrete cover debonding, the load carrying capacity is inadequate. The safety and durability can improve by strengthening the concrete structure. The bond behavior between the near - surface mounted(NSM) fiber rein- forced polymer(FRP) and concrete is presented with pull - out test and beam test at home and abroad in recent years. FRP is lightweight, high strength, corrosion resistance, easy construction etc. and is widely applied in the field of strengthening.
