摘要
结合新疆某行政楼加层加固改造工程实例,对目前几种主要加层方案和加固方法进行了探讨,通过加固前后框架柱轴压比的变化,指出采用在混凝土构件外部粘贴碳纤维布补强技术,不仅提高了柱的抗压强度,而且能有效地改善混凝土柱的轴压比。
Combined some adding-storey and .strengthening reconstruction illustration of a administration building in Xinjiang, a few kinds of main adding-storey scheme and reinforced methods used usually at present are discussed. By comparing changes in axial compression ratio of column before and after reinforcement, authors show that cohesive CFRP strengthening technique outer the concrete structural member can improve the and axial compression ratio of concrete column.
