摘要
外包钢加固混凝土是指用湿式外包钢方法加固轴心受压的混凝土结构。本文从理论上推导了后加钢与原混凝土以及混凝土里面的钢筋之间的应力—应变关系,提出了两种界限状态的概念,并按此概念给出了轴心受压混凝土湿式外包钢加固时,外包钢利用系数的确定方法。
In the article,concrete strengthened by wrapping steel outside refers to strengthening axial compressing concrete structure by wrapping steel outside humidly.The stress-strain relationship between later steel and original concrete and reinforcing steel bar in it is deduced.A new concept of two kind of boundary states is developed.Amethod of defining outer steel utilization coefficient is given in axial compression concrete strengthened by wrapping steel outside.
