Simulation Calculation Analysis of RC Beam Strengthened with Carbon-fibre by Reverse-Arch Method
Pages: 30-33,38
Year: Issue:  1
Journal: Journal of Southwest University of Science and Technology

Keyword:  反拱法RC梁承载能力数值模拟;
Abstract: 采用动力设备将钢筋混凝土梁向上反拱一定的弧度,然后在梁的下部外贴碳纤维布(CFRP),待碳纤维布养护完全后,卸载,此时后加的碳纤维布与原钢筋混凝土梁同时进入工作状态.作者采用分析软件ANSYS模拟此过程,通过与直接用碳纤维布加固RC梁进行比较,得出反拱法加固RC梁能有效提高其承载能力,对类似工程具有一定的借鉴意义.
