MODERN APPROACHES TO IN-SITU BRIDGE TESTING IN THE EXPERIENCE OF UKRAINE AND WORLD PRACTICE
DOI: 10.33868/0365-8392-2025-3-284-26-37
Abstract. The article presents the results of a comprehensive study of the technical condition of a multi-span reinforced concrete highway bridge using a combination of static and dynamic load tests. The testing methodology of an American bridge (according to a published source) and the experience of full-scale testing of a composite reinforced concrete overpass in Ukraine are analyzed. For both structures, the testing program included multi-channel measurements of deflections, stresses and accelerations, identification of modal characteristics, and calibration of analytical models based on field observations.
The comparison of methods demonstrated their similarity and confirmed that the current Ukrainian normative docu-ments remain relevant in relation to international standards and ensure reliable assessment of load-carrying capacity and structural condition. The study emphasizes the need for wider implementation of full-scale testing during commis-sioning of newly built and reconstructed bridges, as well as when more accurate determination of their actual characteristics is required, which will enhance the safety and durability of the transport infrastructure.
Keywords: highway, natural vibration modes, defect, static testing, dynamic testing, stiffness, bridge, modal monitoring, superstructure, technical condition, load-carrying capacity.
