摘要
以双跨门式刚架轻型钢结构为例,从结构选型和支撑布置(屋面支撑和柱间支撑)对结构方案进行分析和比较;对梁柱平面外计算长度取值、柱脚设计以及防腐、防火设计等方面进行介绍;并提出采用PKPM结构设计软件设计时常见问题的解决措施,以及在设计过程中应注意的问题,可为工程设计人员提供参考。
Taking the design of two-span portal frame light-gauge steel structure for example, it is analyzed and compared the design scheme form structure selection and the layout of brace（roof bracing system and that between columns） ;This paper describes the length calculation of beam-column plane exterior, the design of column base and that of anticorrosion and fire protection and so on; put forward a general way adopting PKPM＇s structure design software and discussed some measures to solve problems in design, as well as questions that should be noticed in the process of designing, which can offer some references to designers of projects.
