摘　　要：在加固工程实践中,利用型钢对原有的钢筋混凝土结构(梁、柱)进行加固是一种非常实用的加固措施,加固后的组合梁,其受力性能得到大大改善。本文在6组型钢加固钢筋混凝梁的试验基础上,对试验模型通过ANSYS软件进行了建模和有限元分析计算,对型钢加固钢筋混凝土组合梁的计算原理进行了论证,并提出了有关设计和应用的建议。Today the method by using shaped-steel to strengthen reinforced concrete beam is widely applied to structure projects, it can enhance bending capacity and rigidity of reinforced concrete beam to a great extent. In order to study the mechanical behavior and reinforcing effect of this method, an experiment, in which 6 beams bearing primary load is introduced in this paper. The results with the calculation of ANSYS software, show that the reinforced beam can be greatly improved in bending capacity, bending behavior and rigidity. The researching results not only make the reinforcing theory perfect but also provide practical value to the design theory of concrete beam reinforced with shaped-steel.
