| 摘 要： | 针对外贴纤维增强复合材料(FRP)布加固钢筋混凝土构件通常发生FRP与混凝土表面之间的剥离破坏,使得FRP的强度不能充分利用的问题,提出了一种将外贴法与机械锚固法相结合的新型复合粘结技术(HB-FRP).为了研究复合粘结技术对试验梁的抗剪加固效果,结合在役钢筋混凝土桥梁的损伤特点,本文对16根抗剪试验梁进行了研究,分析...

| Abstract: | To cope with the problem of inadequate utilization of the tensile strength of fiber reinforced plastic/polymer(FRP)due to the failure mode of reinforced concrete members strengthened with FRP sheet,i.e.,the usual debonding between the interface of FRP sheet and concrete,a new hybrid bonding technique(HB-FRP) which combined the externally bonded FRP(EB-FRP)and the mechanically fastened FRP(MF-FRP)was presented.In order to study the effect of new hybrid bonding technique on RC beams in shear resistance,on the... |
