摘要
分析了钢筋混凝土轴心受压构件增大截面加固中的强度折减系数。影响这一系数的因素很多 ,轴压比与原柱截面的配筋率是关键因素。提出了一种确定加固截面强度折减系数的适用方法。
The strength reduction factors are discussed on R.C. column reinforced by increasing section area. A way to define it is presented. The strength reduction factor is not a constant. It is affected by many factors. The ratio Δ N 1( A c1 f c1 ) is key factor. The value of ρ s1 of old column must be concerned.
