Abstract
A bridge is one of the most important structures of man-made construction intended to enable passage across a gap, such as a river, valley, intersection, etc. The bridges can be provided for many purposes, such as facilitating water movement, individuals, vehicles, and railroads. The selection of the bridge's site should consider equity, effectiveness, efficiency, societal benefits, and economic ones. In structural engineering, prestressing methods are frequently used to improve structural components and systems' load-carrying capacity and serviceability. Increases in service loads or the end of a structure's useful life necessitate frequent maintenance and repair work. It is possible to reinforce and repair both steel and concrete buildings. The primary goal of this work is to provide a review of the literature on the assessment of prestressed concrete box girder bridges under static loads as well as investigate the strengthening methods employed by researchers to reinforce prestressed concrete box girder bridges.
