［摘要］济南西部会展中心配套高层结构总高度为188.95m，其下部外围框架柱采用型钢混凝土组合柱，上部框架柱采用钢筋混凝土柱，形成由中央核心筒和外围框架组成的框架-核心筒结构抗侧力体系，结合建筑布置采用双筒结构体系。配套高层结构塔楼平面形状呈内边半径约37.9m，角度约83°的扇形，为超B级高度的超限高层建筑。采用性能化抗震设计对主要构件进行复核，采用YJK和MIDAS Building软件对结构小震弹性、中震弹塑性、大震弹塑性、风荷载作用分析、剪力墙内置钢支撑及楼板温度应力等进行深入分析。结果表明，此结构能满足现行各项规范的要求，具有良好的抗震性能。

Abstract: The total height of the supporting high-rise structure of the Jinan West Convention and Exhibition Center is 188.95m. The lower peripheral frame column adopts reinforced concrete composite column, while the upper frame column adopts reinforced concrete column, forming a frame-core tube structure lateral force resistance system composed of central core tube and peripheral frame. Combined with the architectural layout, the double barrel structure system is adopted. The plane shape of the tower is a fan shape with an inner radius of about 37.9m and an angle of about 83° . It is an out-of-code high-rise building with an ultra-B-level height.The performance-based seismic design was used to review the main components, and YJK and MIDAS Building software were used to conduct in-depth analysis of the structure’s elasticity under small earthquakes, elastoplastic under medium earthquakes, elastoplastic under large earthquakes, analysis of wind load action, steel bracing in shear wall and temperature stress of floor slab.The results show that this structure can meet the requirements of current codes and has good seismic performance. 

Keywords:out-of-code high-rise building； double barrel structure； performance-based seismic design； key component； dynamic elastoplastic analysis
