It is possible to repair the I-shape steel columns in many historic bridges by welding steel plates to their flanges. However, after the column's reinforcing plates have been welded to them, welding residual stresses, initial imperfections and column load can all have a major impact on the strength of the column. A nominal axial resistance is the target for the steel column. The steel column won't be able to support the intended applied load under different conditions, such as changing the building's use from residential to public or storage (additional live loads), and strengthening is thus necessary. Only a few experimental studies on the strengthening of steel columns with welded cover plates are currently available In order to evaluate the strength behavior of strengthening steel columns using steel plates welded parallel to the flange, either parallel to the web or parallel to the flanges and the web combined, this paper provides an experimental and numerical investigation. Twelve specimens were tested using full-scale testing to determine the failure mechanisms, development of stresses, and load-deformation. Every column that was tested had an IPE160 section with a different length. The program ABAQUS/standard v. 6.13 was used to operate the finite element model. Theoretical models correctly predicted the axial load-carrying capacity of the plate- strengthened columns under axially compression loading, as shown by a comparison of the theoretical and experimental data.
