宝能环球金融中心D座塔楼结构设计

Structural Design of D Tower of Baoneng Global Financial Center

合肥宝能环球金融中心D座塔楼地上70层,建筑高度为330m,塔冠约高19m,结构大屋面高度311.4m,采用了带加强层的型钢混凝土框架-核心筒结构体系。本文介绍了该工程结构体系的特点、抗震性能目标、整体弹性计算结果、罕遇地震作用下的动力弹塑性分析结果以及地基基础的设计,对结构设计中的关键问题进行阐述。

The D tower of Hefei Baoneng Global Financial Center has 70 stories on the grounding with a height of 330 m.The height of the tower crown is about 19 m and the height of the structure roof the is 311.4 m.The steel reinforced concrete frame-core tube structure system with reinforced stories is adopted.This paper introduced the characteristics of the structural system of the project,the seismic performance objectives,the overall elastic calculation results,the dynamic elastoplastic analysis results under the rare earthquake and the design of the foundation,and expounded the key problems in the structural design.
