Abstract: The temperature effects of super-long tall buildings under the difference in temperature resulted from day to night are studied. According to the characteristics of the environmentcs temperature change caused by the subrogation from day to night, using the linearity distributing method to calculate the temperature load, the whole temperature effects of the Second Lon-g Distance Telecom Hinge in Zhengzhou are calculated and analyzed through running the current finite element application. Consequently, the whole structural deformation and the scope and the distribution of the internal force or stress of each kind component under such a temperature case have been provided; as compared with the effects under the seasonal descending-temperature case, the reasons in that different temperature cases causing the differences of temperature effects on the super-long tall buildings are given, and the disadvantageous effects caused by the difference in temperature resulted from day to night are summarized. These results may be a references for the design and construction of the project.
