In the Design Code of Reinforced Concrete Structures adopted in this country, the longitudinal bending coefficients in slender members under axial load are determined by empirical formulae obtained from tests. In this paper, the author proposes two simple approximate formulae based upon theoretical analysis and experimental data. For slender members which are eccentrically loaded, the effect of longitudinal bending is usually taken into consideration by introducing an eccentricity magnification factor derived from the theoretical elastic deflection formula, both in the Chinese code and in the USSR Code; but in the calculation of critical loads, some empirical coefficients are introduced. In this paper, the deflection at ultimate load (f_D) is used directly, and two projects for calculation of the value of fp are proposed. By comparing the computed values with the experimental results obtained on about 170 columns, it is shown that the proposed method is more accurate than that used in the current Codes, and is also more advantageous in some other respects.

在我国钢筋混凝土设计规范中,对细长的轴心受压构件的纵向弯曲系数是根据试验得出的经验公式确定的。在本文中,根据理论分析并参考试验资料,提出了一个简单的近似公式。对细长的偏心受压构件,我国和苏联规范都是根据弹性理论的挠度公式导出的偏心距增大系数η来考虑纵向弯曲影响,只是对临界荷载的计算引入从试验中得出的修正系数。在本文中,建议直接改用极限荷载下的挠度f_D来计算,并提出两个计算方案。通过约170根柱的试验结果的计算比较,表明建议方法符合程度较现行规范方法为好,此外还具有一些明显的优点。
