对单层厂房设有两端铰接柱的门架进行了弹性稳定分析，针对铰接柱的不同布置给出了相应的门架柱计算长度系数计算公式。算例验证，公式具有极好的精度，可供设计坡度较大的门架时参考。
The elastic stability analysis was performed on the gantry with hinged columns at both ends of a single storey building. The calculation formula for the calculated length factor of the masts was given for different arrangements of the hinged columns. Examples verify that the formula has excellent accuracy and can be used as a reference when designing a portal with a large gradient.
