【摘要】 采用有限元方法对碳纤维增强复合材料(CFRP)加固H型钢梁进行分析,提出桁架单元模拟粘结层;在此基础上,分别对粘贴不同种类的CFRP加固H型钢梁受力性能进行分析,得出了它们的荷载一挠度曲线、极限承载力和变形,并与试验结果进行对比。两者结果吻合较好,表明本文所提出的建模方法是可行的,可为今后钢结构加固数值模拟实验分析提供参考。更多还原

【Abstract】 Using finite method to analyze H-shaped steel girder reinforced by carbon fiber-reinforced plastic(CFRP),the truss simulate felt layer has been proposed.On this basis,the analysis and study of reinforced H-shaped steel girders strengthened by CFRP under the different types are done.The load-displacement curves,the ultimate loading of H-shaped steel girder and the deformation are presented and compared to the experimental results,the two results are well dovetailed,so the modeling method proposed by this article is feasible.So it can be the reference to the numerical simulation analysis on the steel structure.更多还原
