Information × Registration Number 0210U000673, 0109U007935 , R & D reports Title Researsh of resistance of reiforced concrete constructions of buildings and installations after a long period of outer climatic factors influenc popup.stage_title Head Pozdeyev Sergey, Доктор технічних наук Registration Date 04-03-2010 Organization Academy of Safety named after Chernobyl Heroes of the Ministry of Emergencies of Ukraine popup.description2 Detailed study of results of influence of the open climatic environment on building constructions is actual for fire safety assurance during upkeeping of buildings, which were raised on their base, because nowadays normative documents do not require researches of fire-resistance of such constructions, and buildings, built on their base, put into service like new buildings. The goal of the research - explanation of experiment-calculated method for fire-resistance determination of compression struts of concrete constructions taking into account the influence of environmental natural climatic factors. This method consists of development of effective methods of test methodology of concrete models in the conditions modeled as a result of thermotechnical and static calculations. Expected practical value of researches: - development of experimental technique and getting test data about influence of environmental natural climatic factors on structure and properties of concrete which influences on its conduct in the conditions of high-temperature heating; - development of calculation methodology of fire resistance of compression concrete elements of constructions taking into account the change of their structure under the influence of environmental climatic factors; - getting of test data about compression concrete elements conduct during high temperature heating, efforts and deformations which appear in constructions depending on time of climatic factors influence; - development of effective methodology of results interpretation of model patterns tests for determination of fire-resistance degree of concrete constructions with compression elements.
