Taking the continuous multi-span and multi-slope portal frame as example,this paper analyzed the steel column-removed portal frame.Combined with China current code,the design methods and points of steel column-re-moved portal frame were illustrated.The steel quantity was compared between column-removed portal frame and none column-removed portal frame model.The conclusion was get that the structure form of steel column-removed portal frame is better than traditional none column-removed portal frame.%文章以连续多跨多坡门式刚架为算例，对抽柱门式刚架进行分析，提出了抽柱门式刚架的设计方法。结合我国现行规范对抽柱门式刚架的设计要点进行了说明，同时对比门式刚架中间抽柱和非抽柱模型的用钢量。得出结论：抽柱门式刚架结构形式优于传统非抽柱门刚。
