Abstract: The project of Shanghai Jiushi International Equestrian Center has small volume, small site space and heightlimit, but its functions are complex, the requirements for architectural effect are high, each structural unit has its owncharacteristics. The division and system composition of structural unit were introduced. The reasonable structural systems fordifferent structural units in combination with the project characteristics, structural regularity and prefabrication raterequirements were adopted. By dissimilating the conventional plane truss or space truss, the two steel roofs of equestrianstadium choose the special space truss structure with small steel ratio, which not only ensures that the building effect ismore fit for the characteristics of the project, but also meets the needs of the exposed steel structure roof of the building.The type and degree of overrun of the equestrian field unit were analyzed. The technical measures to effectively controlsafety, the strengthening measures of the overall structure and its weak parts, the expected performance objectives were putforward. The special design and research of three structures were introduced, such as free?form surface large openingspecial?shaped high?grade fair faced concrete shell, equestrian island unit with special?shaped single?layer space steelframe?core tube structure system and group control lifting lamp holder design, and the design suggestions and designparameters were puts forward. The analysis and demonstration results show that the structure has good seismic performance,the seismic design is safe and feasible, and can meet the requirements of normal building functions.
Keywords: equestrian field; special?shaped single?layer space steel frame?core tube structure; spatial surface meshstructure; special shaped fair faced concrete cylinder; over?limit analysis; group control lifting lamp holder
