Study of Consequent Damage of Metal Pivotal Structure on Maintenance in Polluted Surroundings
Study of Consequent Damage of Metal Pivotal Structure on Maintenance in Polluted Surroundings

Summary/Abstract: The paper is related with tends to elucidate various forms of harm generated by space pollution to economy of the region in context of the ideas of Agenda 2000 etc. The study discusses the data of the air pollution and subsequences of damages that are fixed in elements of high-rise metal structures. It adduces some data of factual pollution that is dangerous to high-rise metal structures, location of initial generators of pollutants, interrelations of polluted flows during their migration in the air. Experimental observation reveals the accumulation of micro and local defects, and their joining process. Afterwards aftereffects are discussed as stress concentration around defects, wear and tear of structures, the scattering of strength resources, loss of the durability of single element and the structure in whole. The residual strength of steel elements of structure was tested using standard specimens that had been cut out from the elements of structure at the end of its exploitation.
