摘　　要：采用碳纤维布,对8组木柱(短柱)构件进行环向粘贴碳纤维布加固。通过试验考察了碳纤维布加固对木柱轴心抗压极限承载能力的提高效果;分析了碳纤维布加固木柱的破坏形态及荷载应变关系;通过各组试件试验结果的对比分析了碳纤维布的用量、布置形式对提高轴心抗压承载力的影响。Eight groups of timber columns components reinforced by carbon fiber reinforced polymer（CFRP） with various enwrapping forms have been studied at laboratory. The enhancing effect of their axial compressive bearing capacity and the failure mode are investigated. Based on the data collected in the test, load-strain curves have been drawn and analysed. Finally ,the influence of quantity, space and wide of CFRP on test result is discussed.
