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 ...

Applied Sciences (Switzerland), 2020 Soil-abutment or soil-pile interactions under cyclic static loads have been widely studied in integral abutment jointless bridges (IAJBs). However, the IAJB has the combinational interaction of soil-abutment and soil-pile, and the soil-abutment-pile ...

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.

Transition Slabs of Integral Abutment Bridges
Structural Engineering International, 2011 Over the past decades, an increasing number of bridges with integral abutment have been built in Switzerland. This type of bridge offers various advantages over standard bridges with abutments, equipped with expansion joints and bearings that require regular inspection and maintenance.

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.

Structural Engineering and Mechanics, 2010 In this study, the effect of superstructure-abutment continuity on the distribution of live load effects among the girders of integral abutment bridges (IABs) is investigated. For this purpose, two and three dimensional finite element models of several single-span, symmetrical integral abutment and simply supported (jointed) bridges (SSBs) are built ...

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. This requires that the slab of the bridge to be longitudinally continuous without expansion joints. This causes cyclic displacement

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
