摘要
利用FRP约束混凝土的应力 -应变关系模型 ,采用数值方法 ,对FRP约束混凝土压弯构件的荷载 -变形关系进行了全过程分析 ,据此考察了FRP极限强度、混凝土强度、含FRP率和长细比等参数对该类构件力学性能及承载力的影响 。
Based on the determination of stress strain model of FRP confined concrete,a kind of simplified integral method is applied to calculate the complete curve of load deformation of FRP confined beam columns.The influence of several parameters,such as the strength of FRP composite,the concrete,the FRP ratio as well as slenderness ratio on the behavior and bearing capacity of the beam columns are analyzed.
