南京金融城二期C3塔楼地上49层、地下5层,建筑高度为188.6 m,采用型钢混凝土框架-混凝核心筒结构体系。塔楼平面为近似矩形,在41层楼面处平面收进为一半,为高位不对称立面收进的建筑。针对结构的不规则情况,采取相应的加强措施,提出符合结构特点的抗震性能目标,对整体结构进行了小震、中震及大震的分析,并针对结构的高位立面不对称收进的特点进行了详细的分析。分析结果表明,该结构设计安全可靠,抗震性能良好。
Abstract
C3 tower of Nanjing financial city Phase Ⅱ has 49 floors above the ground and 5 floors below the ground. The height of the building is 188.6m. The steel reinforced concrete frame and concrete core tube structure system is adopted. The plane of the tower is approximately rectangular, half of which set back at the 41th floor. C3 tower is a building with high-position asymmetric elevation retraction. According to the irregularities of the structure, the corresponding strengthening measures are taken,and the seismic performance target in accordance with the characteristics of the structure is set. The frequent earthquake, design earthquake and rare earthquake of the structure are analyzed. In addition, the high-position asymmetric retraction of the structure is analyzed in detail. Analysis results show that the structure design is safe and reliable with good seismic performance.
