【摘要】 提出了T ,L ,┼形双向偏心受压柱正截面承载力的简化计算公式。这些简化公式所描述的N -Mx-My三维相关曲面不但精度高 ,而且光滑、连续 ,具有外凸性 ,简单实用 ,克服了异形柱正截面承截力精确计算耗时太多的缺点 ,为异形柱的工程应用奠定了基础。此法已装入作者开发的混凝土结构设计配筋程序中 ,经十几家设计院几十个工程计算 ,与其它程序相比 ,无论是配筋结果还是计算时间均有所改进更多还原

【Abstract】 Based upon the accurate load bearing capacity N M x M y interaction curves, which are obtained by fiber method, the simple equations of interaction curves are derived for the T,L and ┼ shaped R.C.Columns. These equations give very good approximations to the accurate ones, while maintaining smoothness, convexity and continuity requirements in three dimensional space. The equations may be implemented in the general computer programs for R.C.structures design.更多还原
