摘要
通过8根矩形木梁的静力试验,研究了碳纤维布加固木梁的抗弯性能,包括破坏特性、极限荷载、刚度、截面应变及端部碳纤维布应变等结构性能。试验结果表明,碳纤维布加固木梁具有良好的效果,可为古建木结构的维修加固提供新的方法和试验依据。
According to the static tests of 8 rectangular timber beams strengthened with carbon fiber reinforced polymer （CFRP） sheets, the bending behaviors are studied such as failure characteristics, ultimate bearing capacity, rigidity, strain of timber section and CFRP sheets at the ends. The results show that CFRP sheets have a good strengthening effect for timber beam. This paper supplies a new method and test reference for repairing and strengthening of Chinese ancient timber buildings.
