碳纤维与钢板复合加固钢筋混凝土构件的分析

Finite element method of member of composite rehabititation with bonded carbon fiber reinforced polymer and steel plate

在碳纤维布加固钢筋混凝土矩形梁抗弯试验的基础上,应用有限元方法对其进行了力学性能分析,并与试验结果进行了对比,结果表明,碳纤维布与钢板复合加固后,梁的屈服荷载和极限荷载均有所增长,特别是梁的极限荷载提高效果显著。

Based on the experiments of the bending behavior of simply suplmrted RC beams strengthened by CFRP nonlinear finite element analysis is presented on the mechanics performances in the ANSYS ,soft ware environment. The result show that externally compositc rehabititation with bonded carbon fiber reinforced polymer and steel plate can be effectively used to increase the yielding and ultimate moment of the RC T-beams.
