摘要
利用碳纤维布加固钢筋混凝土构件以提高承载能力及延长寿命是目前比较流行的方法.采用静力平衡关系,利用虚梁法(或称共轭梁法)编制了粘贴碳纤维加固后构件的计算分析程序,获得任意一级加载或位移后的位移和相应的内力,从而达到对加固梁进行全过程分析的目的,计算结果和试验结果吻合良好.
Presently,it is a popular method that carbon fiber cloth is utilized to reinforce R. C members so as to enhance bearing capacity and prolong using life. This paper uses trial and error method of static balance and method of conjugate beam to writes a computation and analysis program for member reinforced with carbon fiber ,which can acquire displacement and relevant internal stress under each loading or displacing, and consequently, realize full-range analysis for reinforce beam. The results from computations agree well with results from trails.
