As the length of the wing walls is increased, they take up more horizontal moments than the abutment wall and the deflection behaviour of the wing walls is way different than that of cantilever wall, and hence, it shows that the design aspects of the wing walls need to be checked. Also, the connected wing walls cause horizontal moments in the middle of the abutment wall, which is an interesting result; as now, it proves that after casting wing walls monolithically to the abutment wall, the design of the abutment wall cannot be done as cantilever wall, and we need to take care of this horizontal moment by providing required rein- forcement. Also, as the length of the wing walls is short, the torsional moments become critical. 1. Introduction e construction of bridges has played a major part in the development of our society and civilization. e bridges nowadays are analyzed and designed very cautiously. e analysis part of the bridge system is much more impotent than the design part. e advancement in the stability analysis of the bridge system has reached the behaviour study of the abutments and the wing walls. Abutments are vertical structures, classified as substructure component of a bridge system. ey are used to retain the earth behind the structure. e abutments are subjected to the dead loads, live loads from the bridge superstructure, and the lateral pres- sures mainly from the approach embankment. In a bridge, the wing walls are adjacent to the abutments and act as retaining walls. ey can be parallel to the bridge deck or perpendicular or may at some angle, depending on the requirements. ey are generally constructed of the same material as those of abutments. e walls can be independent or integral with the abutment wall. e integral wing walls have an influence on the behaviour of the abutment wall; hence, the length, thickness, etc., parameters are adopted carefully after proper design and checks. Wing walls are provided at both ends of the abutments to retain the earth filling of the approaches. e studies about configurations of the wing walls affecting the behaviour of the bridges integral with abutment have shown that the connection between the wing wall and the abutment creates a better stable system Hindawi Advances in Materials Science and Engineering Volume 2022, Article ID 6103595, 10 pages https://doi.org/10.1155/2022/6103595
