Discussion on the calculation of temperature effect of ultra-long high-rise building structure

extra-long high-rise buildings;  temperature action;  Temperature conditions

By analyzing the types of temperature loads that may be experienced in the whole process of high-rise buildings from construction to normal use, using the linear distribution method to calculate the temperature load acting on the building, improving the calculation of temperature action and temperature difference value, summarizing the method of determining the temperature action calculation condition, giving the expression for calculating the horizontal temperature difference of the structure of ultra-long high-rise building, and formulating the temperature action calculation condition of the ultra-long high-rise building structure, taking the main structure of the second long-distance telecommunications hub project in Zhengzhou as an example. The temperature calculation parameters of various temperature working conditions are given specifically. The actual calculation shows that the temperature calculation condition of the ultra-long high-rise building structure given in this paper can meet the temperature calculation needs of the actual ultra-long high-rise building.
