［摘要］对采用竹板加固的7根木梁进行了对比试验研究，其中3根为对比试件，4根为粘贴竹板加固木梁试件。研究结果表明：在梁底粘贴竹板加固后，木梁受弯承载力可提高71%～93%，平均提高83%；初始弯曲刚度平均提高58%；破坏位移平均增加62%；加固木梁跨中截面仍基本符合平截面假定。可见，粘贴竹板加固木梁可大范围推广。

Abstract:The comparative experimental study on 7 timber beams were tested, including 3 reference timber beams and 4 timber beams strengthened with bamboo plates. The test results show that the flexural capacity of timber beams increases by 71%～93% (with an average value of 83%) after strengthened by bamboo plates. The initial stiffness and the ultimate displacement of the strengthened beams also significantly increase by 58% and 62% on average, respectively. The middlespan section of the strengthened timber beams is also in accord with the plane crosssection assumption. This study has shown that strengthening timber beams with bamboo plates is a very promising lowcarbon and convenient technique.

Keywords:timber beam; bamboo plate; strengthening; flexural capacity
