摘　　要：体育场钢结构罩棚的设计普遍采用钢管和H型钢,某市体育场的太极图形的钢罩棚更加突出了悬挑长度较大的特点,钢撑杆采用大直径钢管灌注高标号混凝土的设计方案,更加稳定可靠,但钢结构完成后在空中灌注混凝土更是增加了浇筑的难度。Steel tube and H-shaped steel are widely used in design of stadium steel structure roof, Tai Chi graphic of some city stadium steel awning is more prominent in the characteristic of large cantilever length, steel bar is more stable and reliable with large diameter steel pipe affused by high grade concrete, however, affusion concrete in the space is more difficulty after the steel structure completion.
