摘要
《钢结构设计规范》(GB50017-2003)对于单层厂房框排架柱平面内计算长度采用两种柱顶理想约束假定,即柱顶平移且能自由转动的表D-3计算长度系数和柱顶平移不能转动的表D-4计算长度系数。并未给出柱顶平移但弹性转动的阶形柱的计算长度。采用任何一种柱计算长度系数有可能偏于不安全或者不经济。本文提出了另外两种确定框排架柱的计算长度确定方法。
Two kinds of ideal restriction of the top of the single layer frame column to get the calculation coeffctent in the code for design of steel structure （GB50017-2003）, that is the column calculation coefficient of the column with moving and free rotating top end in table D-3, and the column calculation coefficient of the column with moving and unrotating top eng in table D-4. Do not provide the column calculation coefficient of the column top of the moving and elastic rotation condition. Adopting any kind of these two column calculation coefficients can lead insecurity or uneconomic. This text provides two kinds of methods to approximately make sure the column calculation coefficient of the single layer frame steel-structure column.
