Zonarea factorilor meteo-climatici de risc (valuri de căldură, valuri de frig) în vederea ajustării actelor normative în construcții

Abstract

Extreme climatic phenomena present risk factors for agriculture, health, constructions etc and are studied profoundly these past years using extreme values theory. Several relations that describe pozitive extreme values' probability in GEV and Gumbel distributions are presented in the article. As an example we show the maps of characteristic and reference of some climate parameters (waves of heat, cold waves) with a probability of exceeding per year equal to 0.02, which is equivalent to the mean return interval of 50 years. The obtained results could serve as a basis for elaboration of national annexes to Eurocode 1, parts 3 and 4 in constructions.
