摘要
阐述了在某高层钢筋混凝土框架-剪力墙超长结构设计中所采取的措施,包括设计方案、计算模型、温度计算条件、计算结果的使用、若干设计措施以及上部伸缩缝设置后"一分为二"的"音叉式"柱节点应力分析及设计。通过计算比较和分析认为,工程施工阶段所受到的温度影响最大。弹性内力分析结果应在考虑徐变应力松弛系数之后应用于工程,并建议针对温度应力计算结果宜分段取值进行配筋设计。
The adopted measures for a overlong structure of reinforced concrete frame-wall high-rise 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.
