Integral Abutment and Jointless Bridges [PDF]
Bulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2005 Integral bridges, or integral abutment and jointless bridges, as they are more commonly known in the USA, are constructed without any movement joints between spans or between spans and abutments. Typically these bridges have stub-type abutments supported on piles and continuous bridge deck from one embankment to the other.

Elasto-plastic analysis and optimal design of composite integral abutment bridge extended with limited residual plastic deformation. [PDF]
Sci Rep, 2023 Due to the growing significance of structural theories concerning the composite structure analysed and designed plastically, this paper introduces a new optimisation method for controlling the plastic behaviour of a full-scale composite integral abutment

Safety identifying of integral abutment bridges under seismic and thermal loads. [PDF]
ScientificWorldJournal, 2014 Integral abutment bridges (IABs) have many advantages over conventional bridges in terms of strength and maintenance cost. Due to the integrity of these structures uniform thermal and seismic loads are known important ones on the structure performance ...

Analysis of soil-pile interaction considering slope effect in integral abutment jointless bridges (IAJBs) under cyclic loading. [PDF]
Sci RepThis study systematically investigated the influence of slope effects on soil-pile interaction in integral abutment jointless bridges (IAJBs) under cyclic loading through pseudo-static cyclic tests.

Effects of Geogrid Reinforcement on the Backfill of Integral Bridge Abutments
Buildings, 2023 The construction of integral bridges is one of the most effective methods to reduce bridges’ construction and in-service costs. However, there are associated geotechnical problems with their abutments backfill due to the integrated abutments.
