FRP加固砖砌体墙的试验研究与分析

Experimental Investigation on Masonry Wall Strengthened with FRP

介绍了FRP加固砖砌体墙的试验研究以及受剪承载力分析。通过不同砂浆强度和高宽比的两批试 验,验证了FRP加固砌体墙能够有效提高其抗裂性能,改变破坏形态,提高受剪承载力,使抗震性能得到显著 改善。在此基础上,通过对砌体墙剪切破坏机理和FRP加固作用的分析,针对不同剪切破坏形态提出了受剪 承载力计算方法。试验结果验证,建议公式能够较为准确地计算砌体墙的受剪承载力。

A series of experiments and analysis on masonry wall reinforcement with FRP are introduced.Different motor strengths and walls' sizes were taken into consideration.The experiment results proves that masonry walls can acquire better characters on anti-crack,damage mode,shear capacity and anti-seismic capability.And based on those facts,further analysis explains the mechanism of in-plane shear damage of masonry wall and how the FRP contribute to the wall.Different equations of in-plane shear damage are raised according to two different kinds of damage mode.The calculation results have good accordance with the experiment results and can predict the damage mode.
