摘　　要：针对外粘贴BFRP纤维布加固杨木矩形短、长柱在力学性能上存在差异,以不同粘贴方式、不同层数及不同木柱长度为变量,对杨木矩形短、长柱进行轴压力学性能试验,分析长柱破坏形态、极限承载力、荷载-位移、荷载-应变等。试验结果表明,与未加固杨木矩形长柱比较,BFRP纤维布能较好的约束木柱横向变形,提高了木柱承载力、延性、刚度、变形能力。与杨木长柱比较,横向粘贴BFRP纤维布加固短柱效果优于长柱的加固效果。In this paper,there are differences in the mechanical properties of the short columns of the poplar,and the different columns and the length of the different columns are used as the variables. The axial compression performances of the short and long columns are tested,and the long column failure morphology,ultimate bearing capacity,load-displacement,load-strain and so on are analyzed. The experimental results show that the BFRP fiber can better restrict the lateral deformation of the pillars and improve the bearing capacity,ductility,stiffness and deformation capacity of the columns. Compared with the poplar long column,the effect of stapling BFRP fiber cloth reinforcement is better than that of long column.
