It is discussed that the calculation of the effec ts of the difference of temperature caused by sunlight on super-long tall buildings. On the basis of analyzing the characteristics of the sunlight radiation, the cal culating case of the sunlight action is designed, whose parameters are provided. Using the current finite element analysis application, the whole temperature ef fects of the sunlight action on No.2 Long-Distance Telecom Hinge in Zhengzhou a re studied, meanwhile, the whole temperature distortion and the temperature inte rnal force or stress are calculated and analyzed. Therefore, it is given that th e speciality of the whole structure distortion and the scope and distribution of the internal force or stress of each kind of components under sunlight temperat ure case. These results may be a reference for engineering design and constructi on.
