任意截面钢筋混凝土双向偏压构件非线性稳定性分析的简化法

Simple Method for Nonlinear Stability Analysis of Reinforced Concrete Column with Arbitrary Cross-section Under Bieccentric Compression Loading

将钢筋混凝土任意截面非线性分析方法与Salah提出的段长法结合，将钢筋混凝土双向偏压构件的非线性稳定性分析过程简化。分析中考虑了材料非线性及几何非线性特征，计算公式简便，不需迭代，直接计算即可得到构件稳定性分析的极限承载力。计算结果与试验结果吻合较好。

Based on the nonlinear analysis of arbitrary reinforced concrete cross-sections, nonlinear stability analysis of bieccentric compression mewhers has been simplified with the salah method of segment length. Both material nonlinearity and geometry nonlinedrity are taken into account. The derived formtilas are simple and the ultimate capacity of the member for stability analysis can be directly calculated without iteration. The analyzed results correspond well with the experimental data.
