摘要:南京江心洲AI总部基地由一栋120m高的A塔和一栋78m高的B塔连体组成,其中A塔为框架-核心筒结构,B塔为带屈曲约束支撑的框架-核心筒双塔结构;A塔与B塔分别在低位4~6层和高位17~19层通过跨度36m的钢连廊连为一体,连接节点通过设置铅芯橡胶支座实现,并在高位支座设置黏滞阻尼器以提高抗风和抗震性能。结构存在复杂连接、扭转不规则、楼板不连续、刚度突变、局部穿层柱等不规则情况。对复杂连接多塔结构提出了明确的分析思路;对单塔模型和整体模型进行对比分析,证实了塔楼对连廊的地震放大效应和连廊对塔楼的减震效应;基于大震弹塑性时程分析,掌握了关键构件在罕遇地震下的工作状态,对连接体的关键技术问题如抗连续倒塌等进行了分析。为解决高层结构中多塔复杂连接问题提供了思路。

Abstract: The Nanjing Jiangxinzhou AI Headquarters Base is composed of a 120 m high tower A and a 78 m high tower B conjoined. Tower A is a frame-corewall structure, tower B is a double towers frame-corewall structure with buckling restrained braces; Tower A and Tower B are connected by a steel corridor with a span of 36 m on the 4 th to 6 th floors at the lower position and the 17 th to 19 th floors in the high position.The connection nodes are constructed by setting up lead-core rubber bearings, and viscous dampers are installed on the high-position bearings to improve wind and earthquake resistance. The structures have irregularities such as complex connections, torsion irregular, discontinuous floor slabs, sudden changes in stiffness, and some cross-layer columns. Clear analytical ideas were put forward for complex connected multi-tower structures; the single tower model and the overall model were compared and analyzed, and the seismic amplification effect of the tower on the corridor and the shock absorption effect of the corridor on the tower were confirmed; based on the time-history analysis of the elasto-plasticity of the large earthquake, the working state of the key components under rare earthquakes was mastered. The key technical issues of the connector, such as resistance to continuous collapse, were analyzed, which provides an idea for solving the complex connection problem of multiple towers in high-rise structures.
Keywords: connected multiple-tower structure; out-of-code high-rise building; weak connection; lead-core rubber bearing; buckling restrained brace
