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 elasticplastic 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.
