Abstract:

This paper presents the results of an advanced inspection, structural assessment, and development of rehabilitation and strengthening strategies for Concrete Bridge No. 44, located on National Road N2, Prishtina - Blacë. The primary objective of this study is to identify effective methods for restoring load-bearing capacity and improving the operational safety of the bridge, in compliance with contemporary design standards as prescribed by the Eurocodes, considering the current degradation state of its structural elements and the critical importance of this infrastructure within the national road network. The assessment methodology involved systematic visual inspections, non-destructive testing, and numerically modeled structural analyses to evaluate the existing performance of the main load-bearing beams, columns, and other key components. Based on the collected data, modular and phased intervention proposals have been developed, allowing for the prioritized implementation of repair measures according to the severity of identified deficiencies and the functional priorities of the bridge. The results of this study provide both practical and scientific contributions to the planning of interventions on existing structures built in previous decades, combining modern rehabilitation engineering approaches with international standards of structural design and safety control.
