摘要
现存徽州古建筑大多数受损严重,传统加固方法对木结构易造成腐蚀等问题,采用新型的CFRP材料加固徽州传统木结构,能抑制损坏速度.利用有限元软件对不同CFRP粘贴方式加固木梁进行数值分析和理论值验算并与实验值进行比较分析,依据理论推导出CFRP加固木梁强度验算公式,通过数值分析证明在铺贴位置相同时,增加粘贴层数可有效提高承载力,结果表明:更换榫头部位为全截面粘贴方式是最佳方案.为徽州古建筑木梁加固提供了理论支撑与技术参考.
Most existing ancient buildings in Huizhou have been seriously damaged. The traditional reinforcement methods often cause problems of chemical corrosion on the ancient buildings with wooden structures. The new type of CFRP material is used to reinforce Huizhou traditional wood structure, which can inhibit the damage speed. The finite element software was used to do numerical analysis and theoretical value computation for CFRP bonding, and then to compare and analyze experiment value. Based on the theory, the strength verification formula for CFRP-strengthened wood beams is derived. Through numerical analysis, it is proved that increasing the number of adhesive layers can effectively improve the bearing capacity when the paving positions are the same. The result shows that it is the best method to replace tenon with total cross section bonding. It provides theoretical and technical support for the reinforcement of wooden beams in Huizhou ancient buildings.
