对在实际工程中已经受损的木梁加固后的结构性能进行研究.通过对8根圆形木梁进行静力试验，研究碳纤维增强复合材料（carbon fiber reinforced polymer，CFRP)布加固受损木梁的抗弯性能，包括破坏特性、极限荷载、刚度、截面应变等结构性能.试验结果表明，CFRP布加固受损木梁具有良好的效果,能够有效提高木梁的承载力和刚度.研究结论对碳纤维工程加固的应用具有一定的参考价值.

In practice, most wood beams to be repaired have already been damaged or degraded. It is necessary to study the structural performances of damaged wood beams reinforced by carbon fiber reinforced polymer (CFRP) sheets. Based on static tests of 8 damaged circular timber beams strengthened with CFRP sheets, bending behaviors are studied, including failure characteristics, ultimate bearing capacity, rigidity, and strain of timber section. The results show that CFRP sheets have a good strengthening effect for timber beams. The loading capacity of a timber beam reinforced by CFRP is effectively enhanced. The results are useful to practical design.
