摘　　要：在对六根不同补强钢板厚度、不同锚固措施的钢筋混凝土补强梁进行静力加载试验的基础上 ,研究分析了在静力荷载作用下钢筋混凝土粘钢加固梁的受力、变形性能、破坏形态及底部粘结钢板的受力机理 ,结合试验结果对底部粘钢板加固梁钢板的锚固粘结问题进行了理论分析和试验研究 ;最后 ,针对实际工程中可能遇到的问题 ,对粘钢板加固梁粘贴钢板的锚固措施提出了建议。On the basis of static loading tests of 6 reinforced concrete beams with bonding steel plates of different thickness and different anchorage measures,this paper studies the failure forms and mechanical performance of reinforced concrete beams with bonding steel plates.The strengthening mechanism of the bonding steel plates at the bottom under the action of the static loading is also investigated.Compared with the testing results,the theoretical analysis has been carried out to the problems of the reinforced concrete beams with bonding steel plates and the anchorage of the bonding steel plates at the bottom.Suggestions have been given to the calculation for the reinforced concrete beams with bonding steel plates and the anchorage for the bonding steel plates.
