［摘要］成都大魔方演艺中心小陀螺结构为异形支撑钢框架-混凝土筒体结构，下小上大，造型独特。外围框架呈倾斜向上态势，筒体布置分散偏置，内部竖向构件不连续，层４采用网架结构进行转换。从几何形状和极限承载力两个方面对结构进行稳定性分析，结合弹塑性时程分析结果，对筒体、楼板等有针对性地采取了加强措施，确保了结构体系的合理性。

［关键词］网架；转换结构；极限承载力；结构抗倾覆能力

Abstract: The Music Concert of Chengdu Large Magic Cube Performing Arts Center is like a gyro, which grows greater from bottom to top. The braced steel frame-concrete tube structure system is adopted, and the inclined frame and the tube support the system. As the discontinuity of inner vertical columns, the 4th floor takes grid structure to support the above column. With the stability analysis based on the geometry shape and the ultimate capacity, combined with the elasto-plastic time-history analysis, strengthening measures were adopted on tube and deck etc. to reach a reasonable structure.

Keywords: grid structure； transfer structure； ultimate bearing capacity； resisting overturning ability
