Abstract: . Problem. The limit state method proposed by scientists from Eastern Europe has spread to all countries of the world and has shown its high effi-ciency in the design of construction objects. The limit state method has proven to be well-suited for deter-mining the reliability of a structure. Objectives. The aim of the work is the theoretical substantiation and analysis of reliability concepts, as well as the regulatory and legal framework in the field of de-signing structural and technological solutions based on the principles of the Eurocodes. Methodology. Achieving this objective involves addressing the following tasks: conducting a retrospective and com-parative analysis of key approaches to assessing the reliability of facilities; systematizing regulatory re-quirements for the formation of technological design parameters in accordance with European standards. Results. The study analyzes and proposes the main re-liability approaches and design standards for technologi- cal and structural solutions, taking into account the prin-ciples of the Eurocodes. Originality. The article dis-cusses the most common reliability approaches and design standards for technological and structural solutions. Practical value. Bridge crossings on high-ways are among the most vulnerable structures. The restoration of bridges destroyed as a result of accidents, natural disasters, and during hostilities is of crucial importance for the functioning of Ukraine’s economy and its armed forces. Organizing bridge restoration works on highways remains one of the most complex tasks, involving significant ex-penditures of resources, equipment, and time. At the same time, the primary requirement is that restored bridges must meet reliability standards and be dura-ble. The second generation of the Eurocodes is cur-rently under development, with greater emphasis placed on risk-based design principles. An important cornerstone of the Eurocodes is the target reliability indicators, which define the minimum acceptable probabilities of failure. However, there is a need for a more detailed substantiation of target reliability levels for specific types of structures. The issue of implementing the Eurocodes in Ukraine is pressing for the country’s full integration into the European Union. The proposals initiated by Professor I. Lantukh, unfortunately, have not been fully implemented for the adoption of the Eurocodes. Ukrainian regulatory documents largely remain a calque of Soviet standards, which not only slows down progress but sets the bridge engineering sector of Ukraine back by decades, making it more than 40 years behind modern practice and rendering the construction of extra-class bridges an unattainable goal with an excessively high budget.
