［摘要］郑州华润大厦是高度为166.75m的复杂超限高层建筑，采用钢筋混凝土框架-核心筒结构体系。结构同时具有高度超限、底部错层、平面开大洞和扭转不规则等多项超限。系统地介绍了针对结构中多项超限的对策，根据构件的重要性提出相应的抗震性能目标，并采取相应抗震加强措施。通过不同程序进行了小震弹性分析、中震弹性和不屈服计算，以及大震弹塑性分析。分析表明，提出的抗震性能目标均得到实现。还介绍了基础及节点等的设计。

Abstract: Zhengzhou Huarun Plaza is a super high-rise building with the height of 166.75m. The structural system is RC frame-corewall structure. The building is irregular on many aspects such as height beyond A-level, split-level, big opening, irregular torsion and etc. Countermeasures to solve the above problems were introduced, and the performance objectives of the important components were proposed. Moreover, some structural seismic strengthening measures were adopted in response to these code-exceeding aspects. The elastic analysis under low-level earthquake, the elastic and nonyielding analysis under precautionary earthquake and the dynamic elastic-plastic analysis under high-level earthquake were executed in design. It shows that all performance objectives were satisfied for the building. The design of foundation and joints were also introduced.

Keywords: RC frame-corewall structure; code-exceeding aspect; split-level; big opening; irregular torsion
