对砖墙应用Ⅹ形钢筋网结合喷射高强改性砂浆的加固技术进行研究,通过在低周往复荷载作用下对砖墙加固后的效果进行试验,分析墙体的滞回特性、破坏形态以及变形、耗能、抗剪能力等技术指标,探讨Ⅹ形钢筋网高强砂浆对砖墙加固抗震性能的影响。试验表明,采用Ⅹ形钢筋网高强砂浆加固后的墙体具有很高的极限抗剪承载力,可大大提高原墙体抵抗水平地震作用的能力,结构的变形、耗能能力均增加。
The strengthening technology of Ⅹ steel mesh combined with spray high strength modified mortar for brick wall was studied. The effect of brick wall reinforcement was tested under low cycle reciprocating load, and the hysteretic behavior, failure mode and deformation of the wall were analyzed , Energy consumption, shear capacity and other technical indicators to explore the X-shaped steel mesh reinforced high-strength mortar on the seismic behavior of reinforced concrete wall. The test shows that the wall strengthened with Ⅹ reinforced steel mesh high strength mortar has a very high ultimate shear capacity, which can greatly enhance the ability of the original wall to resist the horizontal seismic action, and the deformation and energy dissipation capacity of the structure increase.
