【摘要】 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。更多还原

【Abstract】 The article introduces a technology of applying X-shaped steel mesh combined with high-strength mortar in the reinforcement of brick walls.Then an experiment was conducted to test the effect after the reinforcement under low-cyclic loading.It analysed was the hysteretic characteristics,failure mode,energy dissipation and shear resistance of brick walls with this strengthening method.And the influence of using X-shaped steel mesh combined with high-strength mortar on the seismic behavior of the brick walls was also discussed.The tests show that using this strengthening method can make the walls own a high degree of ultimate shear strength,and greatly improve the walls’ ability to resist earthquake forces.Structural deformation and capacity of energy dissipation can also be increased.更多还原
