摘要
本文通过14根矩形截面新疆杨木柱的抗压试验,主要研究了BFRP的粘贴层数(一层、两层)和粘贴方式(满贴和间隔贴)对木柱极限承载力、纵向位移和横向挠度等性能指标的影响。结果表明:对新疆杨木柱进行BFRP加固可以提高木柱的极限承载力和纵向延性,其中承载力提高幅度12.1%-94.3%。
In this paper, the compression test with the 14 rectangular cross-section Xinjiang Yang Poplar Columns are carried out. The impact, which the BFRP paste layers (one and two layer) and paste mode (full stickers and spacing paste) on wooden pillars ultimate bearing capacity, vertical and horizontal displacement deflection, etc. are discussed. The results show that the way of the BFRP reinforcement used in Xinjiang Yang Poplar Columns can improve the ductility and vertical ultimate bearing capacity, which can increase 12. 1% - 94. 3%.
