摘　　要：随着使用年限的增加和抗震设防标准的提高,以砌体结构为主的老旧小区房屋老化严重,已不符合现行标准要求,针对城市老旧小区的特点以及补抗震加固改造工作存在的问题,应用新型材料高延性混凝土加固技术,改善砌体结构的抗震性能,提高老旧小区改造经济效益,推动城市有机更新的进程,实现经济的可持续性发展。With the increase in service life and the improvement of seismic fortification standards,the old residential buildings with masonry structure as the mainstay are seriously aging,and they no longer meet the requirements of current standards.Aiming at the characteristics of urban old communities and the problems existing in seismic reinforcement and reconstruction,high ductility concrete reinforcement technology was applied to enhance the seismic performance of the masonry structure,improve the economic benefits of the transformation of old communities,promote the process of urban organic renewal,and achieve sustainable economic development.
