EXPERIMENTAL STUDY ON BENDING BEHAVIOUR OF TIMBER BEAMS REINFORCED WITH CFRP SHEETS
-
摘要: 对粘贴不同数量碳纤维布的同一尺寸木梁进行了抗弯性能的试验,分析了对比梁与加固梁的承载力、挠度等结构性能指标。试验结果表明,碳纤维布对木梁受弯有良好的加固效果。Abstract: A test on timber beams pasting different quantity of carbon fiber sheets was carried out,and it has been analyzed that the performance indexes such as the bearing capacity,deflection,etc of reference beams and reinforced beams.The test shows that the carbon fiber sheets have a good reinforcement effect to the wooden beams.
