| 摘 要： | 通过虚功原理,提出格构柱缀材同时采用缀条和缀板时,绕虚轴的换算长细比计算表达式,并结合实际工程给出算例。计算式综合反映了缀条和缀板对格构柱剪切变形的影响,可供工程设计人员对类似厂房柱设计、加固等借鉴引用。

| Abstract: | According to the principle of virtual work, the formula of conversion slendness ratio of a built-up column with tie plates and cover plates is proposed and the calculation example is also given by combining actual projects. The formula incarnates the effect of tie plates and cover plates on the sheafing deformation of the built-up column. The result may be referenced by designers to design and reinforce similar columns for mill buildings. |

| Keywords: | principle of virtual work built-up column shearing deformation conversion slendness ratio |
