Deck Slab Stresses in Integral Abutment Bridges

Journal of Bridge Engineering, 1999
This study deals with the stress distribution in concrete deck slabs on composite steel beams used with integral abutment bridges. The applied loading is composed of one or more side-by-side HS20-44 trucks. The finite-element method is used to analyze two bridge structures with different numbers of beams, beam spacings, and supporting piles.

Analysis of Curved Integral Abutment Bridges

2010
Deformation of bridges that are induced by thermal loads can be accommodated by expansion joints and bearings. Integral Abutment Bridges have gained acceptance as a way to mitigate potential damage from thermal movements, eliminating the poor performance and maintenance costs associated with expansion joints and bearings.

Parametric Study of Concrete Integral Abutment Bridges

Journal of Bridge Engineering, 2008
A parametric study was conducted to extend the results of an experimental program on a concrete integral abutment (IA) bridge in Rochester, MN to other integral abutment bridges with different design variables including pile type, size, orientation, depth of fixity, and type of surrounding soil, fixity of the connection between the abutment pile cap ...

Integral abutment bridge response under thermal loading

Engineering Structures, 2010
Abstract This paper presents a parametric study and approximate integral abutment bridge (IAB) response prediction models. IABs are complex structures due to the nonlinearity and uncertainties in bridge materials and soil boundaries. Current design specifications and guides do not provide clearly defined analysis methods; therefore, there is a need ...

Monitoring of a Swedish Integral Abutment Bridge

Structural Engineering International, 2011
One of the most commonly discussed problems regarding bridges with integral abutments is the influence of longitudinal elongation of the superstructure as a result of seasonal temperature variation...

Analysis and Prediction for Abutment Behavior of Prestressed Concrete Girder Integral Abutment Bridges

Journal of the Korea Concrete Institute, 2011
This paper discusses the analysis method of prestressed concrete girder integral abutment bridges for a 75-year bridge life and the development of prediction models for abutment displacements under thermal loading due to annual temperature fluctuation and time-dependent loading.

Lateral earth pressure behind an integral abutment

Structure and Infrastructure Engineering, 2009
Integral abutment bridges have gained increasing attention in the past few decades. They provide a cost-effective solution to the high maintenance expenses associated with the joints and bearings found in conventional bridges. This paper describes the observed behaviour of granular soil backfill retained behind an integral abutment subjected to cyclic ...

SEISMIC BEHAVIOUR OF NOVEL INTEGRAL ABUTMENT BRIDGES

NED University Journal of Research, 2019
Integral abutment bridges (IABs) are becoming rather common due to the durability problems of bearings and expansion joints. Monolithic connections between the deck and sub-structure allow, on one side, to increase the structure redundancy and reduce the maintenance costs.

Modeling and Seismic Analysis of Integral Abutments

Structures 2004, 2004
Case studies for integral abutment bridges with skew and with no skew are presented. Unlike conventional single span bridges where seismic forces are neglected, there is a need to consider seismic behavior in single span bridges with integral abutments to help design the buried abutment piles.
