Design of composite bridges with integral abutments

Steel Construction, 2017
AbstractDedicated to Prof. Dr. Akimitsu Kurita on his 70th birthdayBridges are of vital importance to Europe's infrastructure and composite bridges have already become a popular solution in many countries, representing a well‐established alternative to concrete bridges.

An orthogonal component method for steel girder-concrete abutment connections in integral abutment bridges

Journal of Constructional Steel Research, 2021
Abstract To predict the moment – rotation relationships of steel girder-concrete abutment connections with perfobond connectors, this paper develops an orthogonal component method, which is modified from the conventional component method. The connections were first disassembled into several horizontal and vertical components, and these components ...

Field Performance of Integral Abutment Bridge

Transportation Research Record: Journal of the Transportation Research Board, 2000
The behavior of an integral abutment bridge near Rochester, Minnesota, was investigated from the beginning of construction through several years of service by monitoring more than 180 instruments that were installed in the bridge during construction. The instrumentation was used to measure abutment horizontal movement, abutment rotation, abutment pile ...

A probabilistic evaluation of an integral abutment bridge

2016
In last years, a new trend in the construction of short and medium span bridges has raised in some countries. The solution of an Integral Abutment Bridge (IAB), when possible to do, reduces the cost of construction and maintenance because expansion joints and bearings are not necessary.

Evaluation of Seasonal and Yearly Behavior of an Integral Abutment Bridge

Journal of Bridge Engineering, 2007
This paper presents the field performance evaluation of an integral abutment bridge constructed in Massachusetts that was monitored for a period of three years. Emphasis is primarily made on observed seasonal and yearly behavior. Although the bridge abutments were constructed without any skew, differences have been observed in performance between the ...

Pier and Abutment Scour: Integrated Approach

Journal of Hydraulic Engineering, 1997
This paper summarizes many of the results from an extensive program of bridge scour research undertaken at The University of Auckland, New Zealand. An integrated approach to the estimation of local scour depth at bridge piers and abutments, collectively termed bridge foundations, is presented. The design method is based on empirical relations, termed K-

Biofilm Affecting the Mechanical Integrity of Implant-Abutment Joints

The International Journal of Prosthodontics, 2016
This in vitro study evaluated the effect of biofilms on abutment torque loss and wear of implant internal connection surfaces.Morse taper abutments were torqued to corresponding implants and then the implant-abutment assemblies were immersed in a biofilm medium for 72 hours.

Analytical Formulation for Limit Length of Integral Abutment Bridges

Structural Engineering International, 2011
The integral abutment bridge concept has recently become a topic of remarkable interest among bridge engineers, not only for newly built bridges but also for refurbishment processes.

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.

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.
