The Justification of Technical Feasibility of Using Existing Urban Industrial Objects at the Reprofiling of their Appointment

Abstract

Establishment of the valid technical condition, research of relationship of cause and effect and hierarchy of the factors influencing use reliability of load-carrying structures of town-planning objects of industrial function at their reconstruction and reprofiling is the main objective of safe and reliable operation. By method of the atomic and emission spectral analysis it is established that separate elements of farms are made of the “boiling” steel that does not conform to requirements of existing rules. Values of movements, efforts on combinations of loads by snow load and ranges of distribution of potential energy of deformation on farm elements are received. The analysis of intense state of strain of roof frames of covering of the inspected industrial buildings has shown that their bearing capacity in zone of possible formation of snow “bag” from height difference and extension to workshop of higher flight is not sufficient. By results of the conducted researches recommendations for safe further operation of roof frames of covering and valid conclusion about degree of their suitability for the planned conversion and modernization of industrial buildings are formulated.
