摘　　要：门式刚架轻钢结构体系是一种应用比较广泛的钢结构建筑形式,主要采用等截面或变截面的工字钢和轧制H型钢作为梁柱,并以冷弯薄壁型钢作为檩条、墙梁以及墙柱等,以彩钢板作为墙板和屋面板,并配以零件、门窗等形式的相对比较完善的建筑体系。本文通过对门式刚架设计的几个关键问题进行剖析论述,提炼出了门式刚架设计质量的关键控制因素,总结出了门式刚架选材及施工过程中应注意的要点,希望这些设计要点能够指导钢结构设计人员,提高门式刚架的设计科学性。Steel structure of light-weight building with gabled frame is a form of steel building structure which is applied widely. This structure system is relatively perfect, adopting uniform and non-uniform welding H- section steel as beam and column, cold-formed thin-walled steel as the purlin, girt and column, color armor plate as wall and roof, as well as parts, door and window. In the paper, several points of steel design will be analyzed. Initi- ally, the key factors are put forward for controlling the design quality of gabled frame, furthermore, the notes of gab- led frame materials selection and construction are summarized. Ultimately, hopefully, the design points would be guiding the steel structure designers, in order to enhancing the design scientificity of gabled frame.
