摘要
采用几何非线性有限元分析方法分析了蒙皮抗剪刚度、扭转约束、构件长细比和荷载偏心对蒙皮支撑柱基本受力性能的影响。结果表明,蒙皮的支撑作用可以显著减小柱的侧向变形和截面扭转并提高其承载能力,这种作用对于中等长细比及大长细比的构件影响尤其显著。
The effects of diaphragm shear rigidity,rotational restraint,slenderness ratio and loading eccentricity on the basic behavior of diaphragm-braced columns were discussed by the geometric nonlinear finite element method The research results indicate that the diaphragm bracing can reduce the column′s lateral deflection and section rotation obviously,and increase the load carrying capacity,especially for the columns with moderate or large slenderness ratio
