摘　　要：通过 4片碳纤维布加固砖砌体在周期反复荷载作用下受力性能的试验 ,研究了粘贴碳纤维布加固修复砖砌体这种方法的有效性。研究了碳纤维布加固砖砌体的受力特性 ,分析了碳纤维布的用量以及“X”形贴布方式等因素对砖砌体加固效果的影响 ,还提出了碳纤维布加固砖砌体抗剪承载力的简化计算方法。在此基础上 ,进行了碳纤维布加固修复砖砌体的工程实践。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 strip, 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.
