摘　　要：以某工业建筑综合生产车间三跨门式刚架轻型钢结构工程为例,介绍了门式刚架结构的设计过程。通过对比主钢架分别采用Q235B钢材及Q345B钢材的用钢量和对比屋面分别采用简支檩条及连续檩条方案,可知采用Q345B钢材和屋面连续檩条为更加经济合理的方案。通过对门式刚架结构的结构设计分析,为类似的门式刚架结构设计提供参考。Taking the light steel structure project of three-span portal frame in a comprehensive production workshop of an industrial building as an example,the design process of portal frame structure is introduced.By comparing the amount of steel used in the main steel frame with Q235B steel and Q345B steel respectively and the scheme of simply supported purlin and continuous purlin used in the roof,it can be known that using Q345B steel and roof continuous purlin is a more economical and reasonable scheme.Through the structural design analysis of portal frame structure,the paper provides a reference for similar portal frame structure design.
