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来增强砖砌体抗震能力这种加固方法的有效性。本文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贴布方式等因素对砖砌体抗震加固效果的影响。在此基础上，本文提出了碳纤维布加固砖砌体抗剪承载力的简化计算方法，可以满足实际工程设计的要求。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)to strengthen the brick masonry walls for improving their seismic performance is studied. The main factors such as the width of CFS strip, the strengthening manners and other strengthening conditions are analyzed. A simplified design formula is also presented in the paper. The design method can meet the engineering requirements.
