钢筋混凝土轴心受压柱增大截面加固中的强度折减系数取值分析

Analysis on Strength Reduction Factor of Axially Loaded R.C. Column Reinforced by Increasing Section Area

讨论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,提出了一种确定加固截面强度折减系数的方法.影响这一系数的因素很多,轴压比是关键因素,原柱截面的配筋率也必须考虑.

This article deals with the strength reduction factors of axially loaded R.C. column reinforced by increasing its section area. It shows us that the strength reduction factor is affected by many factors and shows us the way to define the strength reduction factors. The ration )/(11ccfANΔis the key factor and the ratio1srof the old column must be concerned.
