FRP筋黏结性能影响因素灰色关联度分析
|
摘要
利用灰色关联度分析理论,对FRP筋黏结性能与混凝土强度、黏结长度和筋材直径三个因素的关联程度进行了分析。得出各因素对FRP筋黏结性能的影响与FRP筋种类有关,GFRP筋和BFRP筋黏结性能关联度依次为:黏结长度、筋材直径和混凝土强度,CFRP筋为筋材直径、黏结长度和混凝土强度。此外还发现,提高混凝土强度等级能有效提高普通钢筋黏结性能,但对BFRP筋、CFRP筋和GFRP筋并不适用。
By summing up the existing research results on the bonding properties of FRP rebars and using the method of grey correlation analysis, the relationship between concrete strength, bonding length and bar diameter and the bonding properties of FRP rebars is analyzed. The show that, the influence of three factors on the bonding performance of FRP rebars is related to the types of FRP rebars. The correlation order of the factors of GFRP or BFRP rebars is the bond length, the rod diameter and the strength of concrete, while the order is the rod diameter, the bond length and the strength of concrete for CFRP rebars. The effective method to enhance the bonding performance of steel bars by increasing the strength of concrete, while is applicable to neither BFRP rebars, CFRP rebars nor GFRP rebars.
