This paper discusses the temperature cases of super-length tall buildings. On the basis of analyzing the possibility of temperature effect during the complete process from constructing to normal using, the linearity distributing method is taken to calculate the temperature effect on buildings. The calculating method of temperature distribution and the temperature difference is improved and the temperature effect cases are summarized. In this paper, the super-length tall building of the second long-distance telecom hinge in Zhengzhou is taken as an example, and calculation parameters of all kinds of the temperature effect cases are given. The calculating results indicate that the temperature cases suggested can satisfy the demand of practical super-length tall buildings.
