针对15根采用间隔粘贴加固方法的新疆杨木矩形截面短柱进行轴心受压试验,研究粘贴不同纤维条带(碳纤维条带和玄武岩纤维条带)和不同加固层数(1层和2层)对其承载力、纵向变形、横向变形等性能指标的影响。试验结果表明:采用不同层数间隔粘贴加固新疆杨木短柱,其承载力和纵向变形都得到了一定程度的提高;木柱的纵向变形和横向变形会随着加固层数的增加分别增大和减小;加固短柱与未加固短柱相比较,其承载力会随着加固层数的增加而提高,其中,粘贴碳纤维情况下的提高幅度为40.8%(1层)和72.2%(2层),粘贴玄武岩纤维的提高幅度为36.1%(1层)和69.6%(2层)。
A total of 15 Xinjiang poplar rectangular cross-section short columns were fixed by using the method of interval gluing and reinforcement. The effects of different fiber strips (carbon fiber strips and basalt fiber strips) and different reinforcement layers (1 layer and 2 layers ) On its carrying capacity, longitudinal deformation, lateral deformation and other performance indicators. The test results show that the load-bearing capacity and longitudinal deformation of Xinjiang poplar short pillars are improved with the ply of different layers, and the longitudinal deformation and lateral deformation of the pillars increase with the number of reinforcement layers and And the bearing capacity of reinforced stub columns increases with the number of reinforced stratums, and the increase rate of stiffened stub columns is 40.8% (1 st) and 72.2% (2 st ), The basalt fiber bonding increased by 36.1% (1 layer) and 69.6% (2 layers).
