REINFORCEMENT OF A BRICK-CONCRETE BUILDING
-
摘要: 某砖混结构教学楼建于20世纪80年代,使用过程中发现存在安全隐患。结合现行规范对其进行了抗震加固设计,确定墙面采用钢筋网水泥砂浆加固,楼面进行增浇钢筋混凝土叠合层加固,并充分做好新旧结构之间的连接。加固后其抗震性达到要求,房屋能安全使用,说明了该种加固方案的合理性。Abstract: A brick-concrete teaching building built in the 1 980s was dangerous. According to current code, the design of anti-seismic reinforcements was carried out. The following reinforcements were done: Adding ferrocement mortar to the wall surface, pouring concrete lamination layer on the precast floor, and connecting new structure with the existing structure.These reinforcement schemes could meet the anti-seismic requirements of current code, mprove the bearing capacity of the structure.The results showed the rationality of the reinforcement schemes
