碳纤维加固钢梁稳定性有限元分析
摘要：随着cfrp的广泛使用，利用它来加固钢结构的研究也越来越深入，但对粘贴cfrp布的钢梁的稳定性研究还较少，本文采用abaqus有限元软件对cfrp布加固工字型钢梁的稳定性进行了分析。结果表明，粘贴cfrp能有效提高工字型梁的稳定性，提高的多少与粘贴的cfrp宽度与厚度密切相关。

abstract: with the widespread use of cfrp, the use of it to reinforce the steel structure of the research is also more and more deeply, but to paste the stability of the steel beam of cfrp cloth is seldom researched, this paper using abaqus finite element software cfrp reinforced cloth to work the stability of the steel beam fonts are analyzed. the results show that paste cfrp can improve the stability of the font beam work, improve the pasting cfrp with how much of the width and thickness closely related.
