Assessment and Inspection of the Technical Condition of Monolithic Reinforced Structures in Transportation Infrastructure Facilities

Abstract

This article gives a short description of an inspection program for concrete and reinforced concrete structures and provides a survey of complex transportation infrastructure facilities on the basis of this algorithm. It contains data on the technical condition of monolithic reinforced concrete load bearing structures used in transportation infrastructure projects obtained by the authors from research re-ports on construction quality monitoring produced by the Scientific Research and Testing Center "MGSU STROY-TEST". Generalization, systematization and analysis of the available data have identified typical damage zones for concrete and reinforced concrete structures. Research findings have identified the need for developing integrated quality assessment and forecasting methods that can be employed in monolithic construction to prevent accidents. These methods will enable evaluation of accident-related risks using the probabilistic logic approach, probability theory theorems and decision-making under uncertainty. Analysis of the causes of defects and damage in concrete and reinforced concrete structures in monolithic construction is today an urgent task. The scale of the problems of reliability and safety of buildings and structures caused by repeated errors in their production and operation, cause significant material damage, injury and death.
