［摘要］大興首開萬科中心為超高層建筑，建筑基本形態(tài)呈切角三角形，結構抗傾覆能力相對較弱，角部設置跨度約15m的斜拉式觀景平臺。結合工程特點，對超高層結構設定合理抗震性能目標，針對該目標提出抗震措施及抗震構造措施。通過調整合適的結構剛度，有效降低核心筒墻體在設防地震作用下的拉應力峰值。對懸掛結構關鍵部位進行水平及豎向的承載力專項分析，并考慮防連續(xù)倒塌要求。結果表明，結構在各地震水準下滿足規(guī)范要求，結構安全可靠。

［關鍵詞］超高層建筑； 性能設計； 懸掛結構； 防連續(xù)倒塌

Abstract:Shoukai Vanke Center is a super highrise building with basic form of cutting angle triangle, the  antioverturning capacity  of the structure is weak, and a 15mspan inclined platform is set up on the corner. Combining with engineering characteristics, seismic performance objectives for the supper highrise structure were set reasonably, and seismic measures and details of seismic design were presented aiming at the performance objective. Through adjusting appropriate structural stiffness, the peak value of tensile stress for the corewall under the precautionary seismic effect decreased effectively. Horizontal and vertical bearing capacities for the key positions of hanging structure were analyzed specially, and the requirement of preventing progressive collapse was considered. The result shows that the structure satisfies requirements of the code under all earthquake levels and it is safe and reliable.

Keywords:super highrise building； performance design； suspended structure； preventing progressive collapse
