Elasto-plastic analysis and optimal design of composite integral abutment bridge extended with limited residual plastic deformation [PDF]
Scientific Reports, 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

Influence of Construction Joint and Bridge Geometry on Integral Abutment Bridges [PDF]
Applied Sciences, 2021 Although integral abutment bridges (IABs) have become a preferred construction choice for short- to medium-length bridges, they still have unclear bridge design guidelines.

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

Analysis of soil-pile interaction considering slope effect in integral abutment jointless bridges (IAJBs) under cyclic loading [PDF]
Scientific ReportsThis 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.

An investigation on the effect of cyclic displacement on the integral bridge abutment
Journal of Civil Engineering and Management, 2014 The integral bridge abutment, as a special type of retaining wall, is subject to cyclic displacement, which is due to the daily and seasonal temperature variations. The frame of this type of bridges is rigid and jointless.

Frontiers in Built Environment, 2022 Expansion and contraction of integral abutment bridges due to temperature changes force integral bridge abutments (IBAs) to move toward and away from the backfill, thus increasing horizontal earth pressures behind the abutments and inducing bending ...

Applied Sciences, 2021 Studies on the seismic response of skewed integral abutment bridges have mainly focused on response under far-field non-pulse-type ground motions, yet the large amplitude and long-period velocity pulses in near-fault ground motions might have significant
