摘　　要：对门式刚架轻型房屋钢结构来说 ,不合理的建筑尺寸往往会导致用钢量的上升和成本的增加。针对不同建筑尺寸和布局、不同荷载的 2 10余个各类门式刚架体系做了分析 ,重点探讨了用钢量与刚架柱距、跨度的关系 。For portal frame light steel structure buildings,unsuitable structural dimensions can usually cause too large steel weight and increasing of investment.Through analyzing the steel weight of more than 210 portal frame systems with different structural dimensions,lay out and loads,the relationship between steel weight and column space and span was emphatically studied.According to the analyzed results,suggestions on suitable initial design were presented.

关 键 词：门式刚架 经济尺寸 优化设计 钢结构 跨度 初设计
