［摘要］ 鳳凰之舟大劇院鋼結構造型復雜，設計難度極大。重點介紹了鋼結構整體穩(wěn)定分析和頸部斜柱穩(wěn)定計算方法。對于鋼結構的整體穩(wěn)定分析，采用了純鋼結構模型和整體結構模型進行不同的屈曲分析，并分別考慮了幾何非線性和雙重非線性的影響；頸部斜柱的穩(wěn)定計算則采用了屈曲分析確定計算長度的方法。結果表明：鋼結構的整體穩(wěn)定和斜柱穩(wěn)定計算均安全可靠。

Abstract: The steel structure of Phoenix Boat Grand Theater is complex in shape and extremely difficult to design. The overall stability analysis of the steel structure and the calculation method for the stability of the inclined column at the neck were emphatically introduced. For the overall stability analysis of the steel structure, the pure steel structure model and overall structure model was used for different buckling analysis, and the effects of geometric nonlinearity and dual nonlinearity were respectively considered. For the stability calculation of the neck inclined column, the method of buckling analysis was used to determine the calculated length. The results show that the overall stability of the steel structure and the calculation of the stability of the inclined column are safe and reliable.
Keywords:Phoenix Boat Grand Theater； overall stability analysis； buckling analysis； geometric nonlinearity； double nonlinearity； calculated length coefficient
