[摘要]黃金國際廣場項目塔樓高度200-1m,采用型鋼混凝土框架-鋼筋混凝土核心筒結構體系。塔樓9層以下建筑平面呈正方形,9~22層外框柱進行了不同方向、不同角度的傾斜,并逐步過渡成上部的風車形平面。介紹了項目的結構特點和超限情況,對結構進行了多遇地震下的反應譜計算和動力時程分析,并進行了罕遇地震下的彈塑性時程分析。對9~22層斜柱層進行了針對性計算,同時采用ANSYS軟件對音叉柱節點進行了應力分析。結果表明,通過采取合適的加強措施,結構可滿足預定的抗震性能目標。

[關鍵詞]超限高層; 抗震性能設計; 斜柱; 彈塑性分析

Abstract:The tower height of Golden International Plaza project is 200-1m. The steel reinforced concrete frame-reinforced concrete core tube structure system was adopted. The building plane below the 9th floor of the tower is square, and the outer frame columns of the 9th to 22nd floors incline in different directions and angles, and gradually transit to the windmill-shaped plane of the upper part. The structural characteristics and overrun of the project was introduced, the response spectrum and dynamic time history of the structure under frequent earthquakes were carried out, and elastic-plastic time history analysis under rare earthquakes was conducted. The inclined column of 9th to 22nd floors was calculated and analyzed, and the stress of the tuning fork column joint was analyzed by ANSYS software. The results show that the structure can meet the anticipated seismic performance target by adopting corresponding strengthening measures.

Keywords:out-of-code high-rise building; performance-based seismic design; inclined column; elastic-plastic analysis
