| 摘 要： | 为研究钢绞线网聚合物砂浆加固砖墙的抗震性能,针对这一加固结构的非线性分析方法,在钢绞线网聚合物砂浆加固砖墙的抗震性能试验基础上,对钢绞线网聚合物砂浆加固砖砌体的界面剥离行为进行专题试验研究。试验结果表明,加固后墙体有良好的延性和抗震性能,但加固层存在剥离现象,使得钢绞线应力发挥小,远低于其极限强度。在试验研究的基础上,提出相应的静力非线性分析方法,考虑界面剥离影响后,采用此方法,可以获得具有下降段的荷载-位移曲线,总体趋势与试验符合较好。 |

| Abstract: | To study the seismic performance of brick masonry wall strengthened with strand mesh reinforcing polymer mortar overlay,and to develop its nonlinear analysis method,experimental study on seismic performance of brick masonry wall strengthened with strand mesh reinforcing polymer mortar overlay was carried out,and then the special experimental study on interface peeling behavior was executed.Experimental results show that the strengthened walls exhibit good seismic performance and ductility.However,there is peeling phenomena between the strengthening overlay and the masonry matrix,leading to the low stress of stand mesh,which is far less than it’s ultimate tension strength.Based on the experimental studies,nonlinear static analysis method for the strengthened brick wall is presented.The load-displacement curve can be obtained with the proposed method,and the trend of analytical results show the good agreement with experimental results. |
