Study of consequent damage of metal pivotal structure on maintenance in polluted surroundings

Jūratė Mockienė, Valerijus Keras, Gintaris Cinelis


The study presented adduces an adoption of the Agenda 2000 ideas. It concerns the field recently studied by A.Kudzys, J.Juocevičius and the authors of this publication. The study also evaluates a standpoint investigating the objects and problems previously discussed by J. Juozaitis, J. Pranevičius and the others (including the authors of present study). It is based on space pollution data set built up in official statistics or publications by B.Kavolėlis, B.Bakutis, M.Lippa, M.Špakauskas, V.Šukytė, E.Zelionkaite and many other authors. The analysis of the current design statements and the cases of damage of high-rise structures used in the open air are also provided in the paper. This is followed by data grouping. The aim is to determine initial sources of pollution, the relations between the pollution flows during their migration etc. The experimental component of this study reveals a formation of micro and local defects, their spontaneous joining that stipulates the stress concentration around defects, and after-effects as the wear and tear of structure, the scattering (loss) of strength resources, loss of the durability of single element and the whole structure. An imitation model is applied for the research which included the reconstruction of conditional monotoneous succession of destruction operations while simulating them sequentially step by step. The reconstruction requires iterative calculations usually named as the Bellman’s damnation of multiversity. However, the processing process of today enables us to perform it with the rate that is acceptable for design practice.
