柱顶无侧移单阶柱计算长度系数的实用计算

CALCULATION OF EFFECTIVE LENGTH FACTOR OF SINGLE-STEP COLUMN WITH NO DRIFT AT ITS UPPER END

本文推导了适用于双跨和多跨单层厂房框架的柱顶无侧移单阶柱的屈曲方程,从而得到上段柱和下段柱的计算长度系数,除列出了μ_2值的数表外,为便于应用,还给出了单阶柱下段计算长度系数的实用计算公式。

This paper derived the buckling equation of single-step column with no drift at its upper end used for double-span or multi-span one-storey shop building.On the basis of the buckling equation,the effective length factor for upper and low sections of the column were obtained.Apart form tabulated values of μ2 Some fonnulae for practical use for determination of effective length factor for low section of the column were given to facilitate application.
