摘要: 冬季運動綜合訓練館為復雜超限高層建筑,建筑高度 30m,采用鋼筋混凝土框架-剪力墻結構. 本工程場館部分、教學及宿舍部分為相對規(guī)則的建筑,因建筑功能及建筑外形等要求,兩部分相對規(guī)則的建筑相互組合,形成通過較少樓板連接的弱連接建筑,同時存在扭轉不規(guī)則、平面開大洞、斜柱等多項平面及豎向不規(guī)則情況. 系統(tǒng)地介紹了針對結構多項超限的設計對策、計算分析方法,根據(jù)構件的重要性提出相應的抗震性能目標,并采取相應抗震加強措施;對弱連接的部位采用零剛度模型進行構件內力分析,按照分析結果對連接部位進行加強處理;對整體模型和分塔模型進行對比分析計算. 結果表明,通過補充分析及多種構造措施加強,結構能滿足預期抗震性能目標要求.

Abstract:Winter Sports Comprehensive Training Gymnasium is a complex out-of-code high-rise building with a height of30m and adopts reinforced concrete frame-shear wall structure. The stadium, teaching and dormitory are relatively regularbuildings. Due to the requirements of building function and building appearance, two relatively regular building arecombined to form a weakly connected building with fewer floors connections, while there are many plane and verticalirregularity such as torsional irregularity, plane holes, inclined columns and so on. The design countermeasures andcalculation analysis methods for multiple overlimits of structures were systematically introduced. According to theimportance of components, the corresponding seismic performance targets were proposed and the corresponding seismicstrengthening measures were taken. The non-rigidity slab model was used to analyze the internal force of the weakconnection parts, and the connection parts were strengthened according to the analysis results. The whole model and thetower model were compared and analyzed. The results show that the structure can meet the expected seismic performancetargets through the supplementary analysis and various structural measures.
Keywords:Olympic Winter Games; performance-based seismic design; out-of-code structure; inclined column; nonrigidity slab; weakly connected structure
