Abstract Bridges are among the most important transportation elements that may be damaged by earthquakes. An integral abutment bridge (IAB) is a linking superstructure directly to substructure. As soil piles, abutments, and superstructures act as combined system resist lateral loading on bridge, stiffness has major impact load distribution. This research attempts determine how structure paramet...

Weaker sections of a railway track, such as the approach sections, are prone to differential settlement under action repeated train loads. The tracks degrade more quickly at critical section adjacent traditional rail bridge because progressive deterioration. Opting for an integral abutment instead is gaining importance due its improved performance in terms track stiffness and reduced settlement...

Although integral abutment bridges (IABs) have become a preferred construction choice for short- to medium-length bridges, they still unclear bridge design guidelines. As IABs are supported by nonlinear boundaries, geometric parameters strongly affect IAB behavior and complicate predicting the response assessment purposes. This study demonstrates effect of four dominant parameters: (1) girder m...
