DESIGN VALUES OF AIR TEMPERATURE FOR REGIONS OF UKRAINE

Abstract

The idea of administrative-territorial zoning is that for the territory of each administrative region a single value of the design parameter of climatic load or impact is set, which will provide the necessary safety margin during the design of buildings and structures in the region.

Administrative-territorial zoning of the design parameters of air temperature was performed according to the data of 371 plain weather stations of Ukraine. From 3 to 29 weather stations are located in the territory of each region. The duration of observations series of air temperature for the vast majority of weather stations is 11… 60 years.

The regional design values of seven air temperature parameters are set for each of the 25 administrative regions of Ukraine and the Southern coast of Crimea: mean annual air temperature, mean air temperature in January and July, temperatures of the coldest and warmest days with a reliability level of 0.98. The results of zoning are summarized in a table, the data of which are recommended for use during the design of buildings and structures.

Statistical analysis of deviations of the established regional design values from the actual values of air temperature parameters at all weather stations showed that the administrative-territorial zoning is performed with a safety margin, and its errors generally do not exceed the errors of tabular or cartographic zoning methods.

The performed administrative-territorial zoning provides convenience, speed and reliability of determining the design parameters of air temperature according to the position of the construction site in a certain administrative region of Ukraine, and therefore can be recommended for use in the buildings design.
