摘 要:以合肥某超长高层框架-剪力墙结构为背景,介绍了温度作用与收缩效应设计及采取的加强措施,研究了结构在温度作用及收缩效应下的变形规律与应力分布特征。结果表明,底部2层收缩变形及楼板应力均较大,3层以上相对收缩变形及楼板应力均很小,可忽略不计。同时对该超长高层结构12~16层仍局部产生了集中裂缝的成因进行了深入剖析,并提出了应对方法和处理措施,可为类似工程实践提供参考。
Abstract: A super long high-rise frame-shear wall structure in Hefei was taken as an example, and the design of temperature action, shrinkage effect and strengthening measures were introduced, and the deformation law and stress distribution characteristics of the structure under the temperature action and shrinkage effect were studied. The results show that the shrinkage deformation and floor stress of the bottom two floors are large, and the relative shrinkage deformation and floor stress above the third floor are small and can be ignored. At the same time, the causes of local concentrated cracks in the 12~16 floors of the super long high-rise structure are analyzed, and the corresponding methods and treatment measures are put forward, which can provide a reference for similar engineering practice.
