【提要】 合肥體育場屋蓋為大型鋼結構挑篷，支承于50個梭形柱上，使用ABAQUS程序計算了該結構的極限承載力，彈塑性計算結果表明，梭形柱的極限承載力在規(guī)范允許的合理范圍。還使用連續(xù)倒塌理論計算了結構在某些梭形柱失效后的極限承載能力，計算結果符合設計要求，整個結構設計合理。
【關鍵詞】 極限承載力分析 連續(xù)倒塌 空間結構 梭形柱
Design of Shuttle Columns and Analysis on Anti\|collapse of Heifei Stadium/Gang Ming,Cheng Jiying,Zhang Sheng,Zhang ChenJun（Beijing Institute of Architectural Design,Beijing 100045,China）
Abstract:Heifei stadium is composed of a huge steel roof which supported by 50 shuttle columns. Software ABAQUS is used to calculate the ultimate strength of shuttle columns. According to elasticplastic analysis result, the ultimate strength of shuttle columns is in the allowable range of the code. Progressive collapse of this project is discussed. It is found that, the ultimate strength of this project when some shuttle columns are invalid can meet the design requirement, which shows that the structure is reasonable.
Keywords:ultimate strength analysis; progressive collapse; spatial structure; shuttle column; stadium
