[提要]  通過(guò)4片碳纖維布加固磚砌體在周期反復(fù)荷載作用下受力性能的試驗(yàn)，研究了粘貼碳纖維布加固修復(fù)磚砌體這種方法的有效性。研究了碳纖維布加固磚砌體的受力特性，分析了碳纖維布的用量以及“X”形貼布方式等因素對(duì)磚砌體加固效果的影響，還提出了碳纖維布加固磚砌體抗剪承載力的簡(jiǎn)化計(jì)算方法。在此基礎(chǔ)上，進(jìn)行了碳纖維布加固修復(fù)磚砌體的工程實(shí)踐。

Based on the test of four brick masonry walls under cyclic loading, the effectiveness of the new method of using the continuous carbon fiber sheet( CFS) on repairing and strengthening the brick masonry walls was studied.  The main factors such as the width of CFS srrip, the X-shaped strengthening manner and other strengthening conditions were analyzed. A simplified design formula was also presented. Finally, a brick masonry wall was strengthened by using the continuous carbon fiber sheet.
Keywords:  carbon fiber sheet; brick masonry wall; repairing; strengthening
