任意约束边界条件下初始缺陷压杆的稳定性分析

Analysis of Stability of Column with Initial Imperfection and Arbitrary Supported Ends

对各种边界条件下初始缺陷压杆的稳定性进行了系统的研究,讨论了不同边界条件和初始挠度对压杆稳定性的影响,得出了求解弹性边界约束系数、端点转角、端点弯矩和压杆挠度的公式,为进一步的理论分析打下了基础。

In this paper the stability of a compressed column with initial imperfection and arbitrary supported ends is studied systematically. The effect of different boundary condition and initial deflection is discussed; the formula of elastic restraint coefficient, end angle, end moment,and the deflection of column are obtained.
