摘要 通过利用大型通用有限元软件ANSYS,对钢筋混凝土(RC)试件梁的5种碳纤维布粘贴方案的抗弯性能,进行了非线性有限元分析。结果发现,屈服荷载和极限荷载的计算值与实测值吻合得很好。这说明通过选用适当的ANSYS单元类型和设置合理的参数,完全可以实现对粘贴碳纤维布加固钢筋混凝土结构的”虚拟试验”。本文目的是确定一些具有共性的参数,以便于其它情况的分析。 In this paper, a finite element method is used to analysis the anti-bending function of the beams using ANSYS program. As a result, the value of the yield loads and the ultimate loads are consisted with the actual loads . It can completely carry out" virtual test"through choosing the appropriate ANSYS element type and the reasonable parameters.
