钢筋砼不等肢L形异形柱承载力的理论研究

Theoretical research on strength of arbitrarily inequiaxial L-shaped R.C. columns

在试验研究的基础上 ,根据钢筋砼双向偏心受压构件的工作机理 ,编制了一套不等肢 L形截面正截面分析的数值迭代法计算机程序 ,不但能得出正截面承载力的 N -M及 Mx-My相关曲线 ,而且能用来计算不等肢 L形截面钢筋砼双向压弯构件的极限承载力和计算配筋 ,理论分析结果与试验结果的分析表明 ,二者吻合较好 .最后提出了确定不等肢

Based on test and the behavior of R.C. columns subjected to biaxially eccentric loading, a computer program of numerical iterative method for the strength analysis of inequiaxial L shaped cross section was specially compiled. With this program, We can not only gain N-M and M x-M y interrelated curves, but also calculate ultimate strength and reinforcement of R.C. columns with inequiaxial L shaped cross section. The comparison between theoretical results and experimental results shows satisfactory agreement. Finally, a practical designing method was put forward for determining ultimate strength and reinforcement of R.C. columns with inequiaxial L shaped cross section.
