［摘要］設置加強層對于結構的受力特性及破壞特征有較大影響，因此加強層的設置合理與否對于實際工程的意義重大。對一棟250m高的鋼筋混凝土框架核心筒結構在不同樓層設置加強層的方案進行建模，并對結構進行小震彈性反應譜法分析、大震靜力彈塑性分析及經濟效益分析，從結構的抗震性能與經濟效益的雙重角度得出250m高鋼筋混凝土框架-核心筒結構的加強層設置結論與建議。［關鍵詞］鋼筋混凝土框架-核心筒結構; 加強層設置; 抗震性能; 經濟效益分析中圖分類號：TU375，TU318 文獻標識碼：A 文章編號：1002-848X(2015)17-0005-05Analysis on strengthened storey setting of 250m high reinforced concrete frame-core tube structures in Guangzhou areaHan Jianqiang1, Chang Wenfeng2, Luo Qin1(1 Guangzhou Design Institute, Guangzhou 510620, China; 2 Guangzhou Civil Architecture Research & Design Institute, Guangzhou 510055, China)Abstract: Because the strengthened storey setting has great effect on the mechanical feature and failure characteristic of structures, hence, whether the strengthened storey setting is rational or not is significant to project in practice. The models of a 250m high reinforced concrete frame-core tube structure with strengthened storey in different storeys were built and analyzed by using response spectrum method under frequent earthquake and Pushover method under rare earthquake respectively as well as the economic benefits. Conclusions and suggestions for the setting of strengthened storey to 250m high reinforced concrete frame-core tube structures were got from the respects of structural seismic performance and economic benefits.Keywords: reinforced concrete frame-core tube structure; strengthened storey setting; seismic performance; economic benefit analysis
