摘　　要：根据使用材料的特性和试验结果，详细分析了增强木梁的受力机理；分析了各设计参数对试件工作性能的影响．研究结果表明：采用钢筋对受弯木梁进行增强是有效的，增强的效果与受拉区配筋率、木梁的高宽比以及增强方式有关；增强木梁的受弯承载力随受拉区配筋率的增加而增加，在配筋率相同的情况下，木梁截面的高宽比越大效果越好；预应力增强工程木梁比非预应力增强工程木梁对承载力的提高更为有效．Through an experimental study on engineering wood enforced by steel, this paper conducts a detailed analysis on the mechanism of the load carrying capacity of the enforced wood and the influence of the design parameters on the test piece on the basis of the features of the materials and phenomena. This study suggests that firstly, steel contributes to bending of the wood, which is closely related to steel ratio, the aspect ratio of the wood as well as the way it enforced;secondly, the bearing capacity of the enforced wood is proportional to steel ratio, which is better with a larger aspect ratio;thirdly, the pre-stressed wood owns a stronger bearing capacity.
