碳纤维布加固带门洞砌体墙片试验研究

Experimental Research on the Brick Wall with a Door Strengthened by Carbon Fiber Sheet

对碳纤维布加固带门洞墙片在低周期往复荷载作用下的抗震性能进行了试验研究,通过对比加固前后所得的各项试验数据,分析了碳纤维布加固对该类砌体结构抗震性能的影响,并比较了不同方案的加固效果。研究表明,碳纤维布对提高墙片抗震性能效果明显,尤其是“X”型粘贴方式能显著提高墙片的抗震承载力。

Based on the experiment of several brick walls with a door strengthened by carbon fiber sheet under cyclic loading, the strengthened effect on the seismic capacity of the walls was studied through the comparison of the data of the wall before strengthened and the strengthened one. The different effects of different strengthening ways were compared as well. This research indicated that the seismic capacity of the walls was improved effectively by carbon fiber sheet attached to them especially the sheets in a shape of “X” which can enhance the ability of the walls obviously to assume seismic loads.
