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．
