摘　　要：轻钢门式刚架结构应用具有经济效益高、施工速度快、结构自重轻、用钢量少、柔性强、刚架跨度大等优势。结构在设计成型后，几何非线性特征显著，且存在较大挠度变形。为实现最少用钢量，优化设计了门式刚架。Light steel portal frame structure has advantages of high economic efficiency, fast construction speed, light weight structure, less steel consumption, strong flexible, big rigid fra-me span, and so on, structure after molding the design, geom-etric nonlinear characteristics became significant, and there are large deflection deformation. In order to achieve the minimum amount of steel, optimize the design of portal frame.
