Abstract
Methods for determining the characteristic values of climate loads at the location of a building have been perfected. Based on comparative analysis, the method of levelling the values of climate loads with an exponential or triangular weight function is recommended. For four climate loads, appropriate equalization intervals are determined, ensuring the maximum amount of weather data taken into account, while maintaining their uniformity. In construction, the determination of the climate load is important for the location of the building. When prescribing building standards, the values of the climate load are determined according to the data of weather stations in relative proximity, which provides values within the limits of reliability. Such an approach can lead to an overestimation of the characteristic values of climate loads and consequently increase the consumption of the construction materials of the building or, in the opposite case, decrease the unnecessarily high-energy consumption to condition the space inside the building.
Highlights
When designing load-bearing building structures, the calculated values of climatic loads are determined according to the norms [1, 2, 3]
Zone maps are given in norms, in which the territory of the country is divided into several regions with determined load values for the area of the region
This leads to an overestimation of the characteristic values of climate loads and an increase in the consumption of the construction materials of buildings
Summary
When designing load-bearing building structures, the calculated values of climatic loads are determined according to the norms [1, 2, 3]. District load values are determined according to the data of individual weather stations in such a way that for certain parts of the region, they provide certain values within the confidence limits. In many cases, this leads to an overestimation of the characteristic values of climate loads and an increase in the consumption of the construction materials of buildings. Samples of the annual maximums of the respective climatic parameters are used for this, which can be described by the Gumbel distribution [4] The methodology of such calculations is described in [5, 6]. Appropriate climate loads during the checking of the calculation of exploited structures may in some cases make it impossible to perform or reduce the laborious and costly work of reconstruction
