摘要:
在对现有裂损木柱加固技术分析研究的基础上，本文提出预应力钢带加固裂损木柱技术．对6个预应力钢带加固木柱和1个未加固木柱的轴心受压性能进行了试验研究，研究钢带间距和层数对试件受力性能的影响，对各试件的破坏形态、承载能力、刚度和延性进行分析．试验结果表明：预应力钢带加固后，木柱的承载力有明显提高，提高幅度在10 %～30 % 之间，延性性能也得到提高．最后，对预应力钢带加固木柱与FRP加固木柱的试验结果进行了对比分析．
Abstract:
A new method of retrofitting the split wooden column with prestressed steel strips was proposed based on the analysis and navigation of the existing retrofitting methods. Experimental study on 6 wooden column retrofitted with prestressed steel strips and 1 wooden column without retrofit were performed.The influence of steel strips space and layers on the mechanical performance of strengthened wooden column were studied, By observing the final failure mode of reinforced wooden column and analysing the change of the bearing capacity,ductility and stiffness. The results indicate that the bearing capacity of strengthened wooden columns is higher than that of unreinforced columns with an amplitude of 10 % ～30 %,and the ductility perfo rmance also has a betterment.The strengthen effect of prestressed steel strips reinforced wooden columns was probed and co mpared to the conventional way by FRP wrap
