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...

Geosynthetic-reinforced soil (GRS) technology has been used worldwide since the 1970s. An extension to its development is application as a bridge abutment, which was initially developed by Federal Highway Administration (FHWA) in United States, called GRS—integrated system (GRS-IBS). Now, there are several variations of this technology, includes GRS Integral Bridge (GRS-IB) Japan 2000s. In stud...

This study measured the screw joint preload of the implant-abutment interface for 7 common hex-top abutment systems. Increasingly, prosthetic designs are utilizing a direct prosthetic connection to the implant, placing the implant-abutment screw joint under direct functional loads and moments. Sufficiently high screw joint preloads are required to maintain screw joint integrity and confer clini...
