摘　　要：为研究碳纤维及钢条加固墩接木柱的可行性,通过受力分析和等效应力模型等理论计算结果制作了3组不同试件,经对试件的抗弯试验,研究碳纤维布和钢条加固墩接木柱的破坏形式以及抗弯性能的差异,并对试验结果进行比对分析,得出2种木结构加固方式从理论到实际应用基本可行,总结的经验可供借鉴。To study the feasibility of strengthening pier connected wooden columns with carbon fiber and steel bars,three different sets of specimens are made based on theoretical calculations such as stress analysis and equivalent stress models,and bending tests are performed on the specimens to study the failure forms and diferences in bending performance of pier connected wooden columns strengthened with carbon fiber cloth and steel bars.The comparative analysis of the experimental results shows that the two types of wood structure reinforcement methods are basically feasible from theory to practical application.The summarized experience can be used for reference.
