［提要］闡述了在某高層鋼筋混凝土框架剪力墻超長結構設計中所采取的措施，包括設計方案、計算模型、溫度計算條件、計算結果的使用、若干設計措施以及上部伸縮縫設置后“一分為二”的“音叉式”柱節(jié)點應力分析及設計。通過計算比較和分析認為，工程施工階段所受到的溫度影響最大。彈性內力分析結果應在考慮徐變應力松弛系數(shù)之后應用于工程，并建議針對溫度應力計算結果宜分段取值進行配筋設計。
［關鍵詞］超長結構；溫度應力；設計措施

Abstract:The adopted measures for a overlong structure of reinforced concrete framewall highrise structure are introduced, including design project, analysis model, conditions of temperature calculation, utilization of calculation results, some design measures, the node stress analysis and design of “Y" shape column formed by contractility joint. Through calculation comparision and analysis, it is concluded that the internal forces at construction period are influenced greatly by temperature, and the analysis results of elastic internal forces considering creep relaxation coefficient are applicable to engineering.
Keywords:overlong structure; temperature stress; design measures
