摘要
FRP筋与混凝土间的粘结性能是FRP筋与混凝土共同工作的基础,为充分利用FRP筋强度高的优点,避免粘结破坏,必须找出FRP筋与混凝土间的粘结滑移规律。文中基于连续曲线模型,采用特殊单元模拟FRP筋与混凝土间的粘结滑移,通过有限元分析,归纳出FRP筋与混凝土间的粘结滑移规律。
Concrete members prestressed by fiber reinforced polymer/plastics have some advantages such as good durability, and are widely applied recently. The adhesive property between FRP and concrete is the foundation of their joint work. To make good use of high strength of FRP and avoid cementation destruction, we must find out the law of bond-slip between FRP and concrete and then provide theoretical basis for the stress performance research of FRP concrete＇s components. Based on full curve model, useing special units to simulate the bond-slip between FRP and concrete, the paper concluded bond-slip law through finite element analysis.
