摘要:
FRP剥离破坏是FRP加固结构中较为常见的一种破坏模式，其脆性的破坏特征很大程度上限制了FRP这一高性能材料在加固领域的应用．之前的研究已经证明施加适当的锚固措施能有效的控制和延缓剥离破坏的发生，提高加固效果．FRP束锚固件是一种将FRP布滚卷或折叠后通过树脂胶植入预钻孔洞的锚固措施．但是目前针对其锚固性能的研究还不完善，尤其针对其与砌体材料之间锚固性能的研究还很匮乏．相比FRP束锚固混凝土试件，砌体材料(例如烧结粘土砖)由于尺寸较小会对其锚固性能产生很大影响．本文针对FRP束与砌体材料的锚固性能进行深入研究．首先针对FRP网格加固砌体结构优化了锚固件构造方式，进而采用拉拔试验方案，分析研究了FRP束锚固砌体材料的力学性能及其破坏机理，并通过试验研究分析了锚固件主要参数与锚固强度的相关关系，最后依据试验结论提出了相应设计建议．
Abstract:
Fiber reinforced polymer (FRP) anchors made from rolled or folded fibers have been shown to be effective for delaying or even preventing premature debonding failure in FRP strengthened concrete structures through externally bonding. This study explores the application of FRP anchors in the FRP strengthening of brick masonry structures. One of the features of such a system is that the brick unit has smaller dimensions compared to common concrete specimens. This paper reports an experimental study on these FRP anchors under pull-off loading. Test parameters include anchor construction, the geometry of pre-drilled holes and FRP anchor itself. The experimental results indicate that FRP anchors can be designed to achieve higher loading capacities and hence is expected to effectively prevent or delay FRP debonding failure. The results also indicate that the geometry of the pre-drilled hole has significant effects on the anchorage strength
