［摘要］青島深藍中心1號綜合塔樓地上共74層，建筑高度328-60m，采用框架-核心筒-外伸臂鋼桁架結構體系。外框架為型鋼混凝土柱與鋼梁，為了增加弱軸抗側剛度，東西立面框架柱間距加密，且由鋼筋混凝土核心筒與周邊框架組成雙重抗側力體系。塔樓采用3m厚整體筏板基礎，局部采用巖石錨桿抵抗水浮力。針對項目的特點和超限情況，對結構小震彈性、中震彈塑性、大震彈塑性及關鍵節(jié)點等進行深入分析，結果表明，結構能滿足所設定的抗震性能目標，具有良好的抗震性能。

Abstract:The No.1 complex tower building of Qingdao Shenlan Center has 74 floors overground with architectural height of 328-60m, and it adopts structural system of frame-corewall-steel outrigger. The outer frame comprises steel reinforced concrete columns and steel beams. In order to increase the lateral stiffness of the weak axis of the structure, the frame spacing of columns in both of the East and the West facades are encrypted, and the dual lateral resisting force system is composed of reinforced concrete corewall and surrounding frame. The tower adopts 3m thick integral raft foundation, and local rock bolts are used to resist water buoyancy. According to the characteristics of the project and the out-of-code situation, the elastic analysis was conducted on the structure under frequent earthquake, elastic-plastic analysis was conducted on the structure under fortification and rare earthquakes, and key nodes were analyzed in depth. The results show that the structure can meet the expected seismic performance goals, and has good seismic performance.
Keywords:Qingdao Shenlan Center; super high-rise structure; outrigger; belt truss; seismic performance
