Analysis of regulatory documents regarding data collection for probability calculations of reinforced concrete structures

Introduction. A sustainable system of risk management in construction is in great demand for both consumers and suppliers of construction products. As one of the main elements of such a system, probability calculations of loader-bearing structures provide a necessary level of reliability and optimality of construction solutions. At the same time, the transition towards risk-oriented design, including the assessment and management of risks, implies the presence of sufficient statistic data, along with the methods of data collection and probability modeling. This study is focused on the issues concerned with collecting data for probability calculations.

Aim. To propose suggestions for improving the national regulatory framework as related to probability calculations of reinforced concrete structures and collecting the necessary data.

Materials and methods. The main objectives of the study were to investigate and analyze Russian and foreign experience in the field of risk assessment and management in terms of building structures and facilities based on probability calculations. In order to achieve these objectives, an analysis of existing Russian and international documents was carried out. In the course of the study, national regulatory legal acts and standardization documents including codes of rules and GOSTs were considered. In addition, some national regulatory technical documents, which were not included in the lists of both obligatory and non-obligatory applications, were analyzed, as well as other specialized regulatory technical documents. An analysis of foreign regulatory technical documents was conducted, including those regulating the initial data characteristics to perform probability calculations (loads, materials, and calculation models). In general, the methodology for analyzing regulatory technical documents involved a detailed study of the selected documents, an analysis of their positions concerning the issue under consideration, as well as an assessment of the completeness and sufficiency of the positions of the documents concerning the methods for determining the initial data characteristics for probability calculations of reinforced concrete structures regarding loads, materials and calculation models.

Conclusions. On the basis of the conducted analysis, specific subject areas for research works are formulated focusing on the development of probability calculations of reinforced concrete structures. A system of regulatory documents is proposed enabling an optimal risk-oriented design of reinforced concrete structures to be implemented.
