摘要:昆明春之眼商业中心主楼建筑高度407m,为抗震设防烈度8度区建筑高度超400m的超高层建筑之一,主楼采用巨型支撑框架-钢筋混凝土核心筒结构体系。主要介绍了主塔楼结构设计关键点,包括结构体系、黏滞阻尼布置、消能减震设计、地基基础的设计等;采用了屈曲约束支撑BRB、柱间黏滞阻尼器及悬臂黏滞阻尼等措施进行消能减震设计,采用弹塑性时程分析验证了消能减震措施的有效性。同时对不同施工顺序进行了模拟分析。结果表明,不同的施工顺序对不同类别构件的均有一定影响。设计中需对施工顺序予以重视。在基础设计中则着重关注了基岩起伏对塔楼不均匀沉降的影响,采取增补抗压桩和后注浆增强的形式对基岩埋深较深的区域进行加强,保证其沉降满足规范要求。

Abstract: The architectural height of the main building of Kunming Eye of Spring Commercial Center is 407 m. It is one of the super high-rise buildings with a building height of more than 400 m in 8-degree seismic fortification intensity region. The main building adopts structural system of mega braced frame-reinforced concrete core. The key points and overall structural index of the structural design of the main tower were introduced, including structural system scheme, viscous damping layout, energy dissipation and damping design, foundation design, etc. The seismic energy dissipation design and shock absorption was carried out by adopting measures such as buckling restraint bracing BRB, inter-column viscous damper and outrigger viscous damping. Elasto-plastic analysis was carried out to verify the efficiency of energy dissipation measures. At the same time, different construction sequence was simulated and analyzed. The results show that different construction sequences have a certain impact on different types of structural members. Attention should be paid to the construction sequence in structural design. In the foundation design, the impact of bedrock undulation on the uneven settlement of the tower was paid attention to. The areas with deeper bedrock buried depth were strengthened by supplementary compression piles and post-grouting reinforcement to ensure that the settlement meets the specification requirements.
Keywords: super high-rise building; mega braced frame; seismic energy dissipation design; viscous damper; construction sequence; uneven settlement
