采用灌胶加固的方式对6根带有干缩性裂缝的新疆杨木矩形截面短柱进行轴心受压试验,研究结构胶对木柱极限承载力、横向和纵向应变、纵向变形和横向变形等性能指标的影响。试验结果表明,相对于未加固柱,采用结构胶加固木柱,其极限承载力提高了15%左右,纵向变形和横向变形都得到了一定的改善,表明采用灌胶加固的方式对加固要求不高的构件在一定的范围内是可行的。
Six compression tests of Xinjiang poplar rectangular cross-section short columns with shrinkage cracks were carried out by means of potting and reinforcement to study the effect of structural adhesive on the ultimate bearing capacity, transverse and longitudinal strain, longitudinal deformation and transverse deformation And other performance indicators. The experimental results show that the ultimate bearing capacity of structural columns strengthened by the structural adhesive is about 15% higher than that of the unreinforced columns, and the longitudinal deformation and lateral deformation have been improved to some extent. High components are feasible to a certain extent.
