摘　　要：某超限高层梁柱节点核心区混凝土由于浇筑原因,其强度无法达到原设计混凝土强度等级,需进行加固处理。文章阐述了常用的加固手段及预应力加固梁柱节点核心区的方法,浅述了预应力加固梁柱节点核心区的一些注意事项。Due to pouring,the strength of the concrete in the core area of a high-rise beam column joint can not reach the original design strength grade,so it needs to be strengthened.This paper describes the common reinforcement means and the method of prestressed reinforcement of beam-column joint core area,and briefly describes some matters needing attention of prestressed reinforcement of beam column joint core area.

关 键 词：钢筋混凝土梁柱节点 预应力加固 加固注意事项
