“…Besides, it seems that the length of the as-built bridge, i.e. 177.5 m, is lower than the maximum allowable length of integral bridges referred by Dicleli and Albhaisi [51,52]. It follows that the steel piles, used for the construction of the restraining system, can sustain the imposition of the deck's cyclic thermal displacements.…”

“…Soil-pile interaction is usually exerted by the interaction between pile stiffness and sounding soil stiffness. Many previous studies [2,8,10,11,13,15,26,27,33,34,37,39] reported that soil-pile interaction is a key variable to determine IAB behavior. However, several boring tests are performed before bridge design, thus properties of surrounding soils have uncertainties.…”

“…Kim et al [15] also demonstrated that superstructure material property, i.e., thermal expansion coefficient, significantly influences bridge response thus state agencies in the United States and other countries limit the length of IABs depending on girder material [1]. Although Design Manual Part 4 by Pennsylvania Department of Transportation (PennDOT DM4) [34] limits the IAB bridge length to 180 m for concrete and 120 m for steel, Dicleli and Albhaisi [35] reported bridge length limitation for moderate climate at 260 m for concrete and 180 m for steel girder. Baptiste et al [9] performed numerical analyses and found that a 457 m long concrete girder IAB with strong pile axis orientation satisfied maximum pile stress limitation.…”

Influence of Construction Joint and Bridge Geometry on Integral Abutment Bridges

Although integral abutment bridges (IABs) have become a preferred construction choice for short- to medium-length bridges, they still have unclear bridge design guidelines. As IABs are supported by nonlinear boundaries, bridge geometric parameters strongly affect IAB behavior and complicate predicting the bridge response for design and assessment purposes. This study demonstrates the effect of four dominant parameters: (1) girder material, (2) bridge length, (3) backfill height, and (4) construction joint below girder seats on the response of IABs to the rise and fall of AASHTO extreme temperature with time-dependent effects in concrete materials. The effect of factors influencing bridge response, such as (1) bridge construction timeline, (2) concrete thermal expansion coefficient, (3) backfill stiffness, and (4) pile-soil stiffness, are assumed to be constant. To compare girder material and bridge geometry influence, the study evaluates four critical superstructure and substructure response parameters: (1) girder axial force, (2) girder bending moment, (3) pile moment, and (4) pile head displacement. All IAB bridge response values were strongly related to the four considered parameters, while they were not always linearly proportional. Prestressed concrete (PSC) bridge response did not differ significantly from the steel bridge response. Forces and moments in the superstructure and the substructure induced by thermal movements and time-dependent loads were not negligible and should be considered in the design process.

“…This restraint is not related to the seismic action, but mostly with the in-service induced movements of the deck, which become significant in bridges with total lengths greater than 150 m according to the limits imposed by various transportation agencies also described by Dicleli and Albhaisi (2004). It was, finally, decided that the work should be restricted to overpasses and typical small, and intermediate span continuous deck bridges, that is, with a total length of, say, 150 m.…”

Seismic design of isolated bridges involves conceptual, preliminary and detailed structural design. However, despite the variety of commercial software currently available for the analysis and design of such systems, conceptual and preliminary design can prove to be a non-straightforward procedure because of the sensitivity of bridge response on the initial decisions made by the designer of the location, number and characteristics of the bearings placed, as well as on a series of broader criteria such as serviceability, target performance level and cost-effectiveness of the various design alternatives. Given the lack of detailed design guidelines to ensure, at this preliminary stage, compliance with the above requirements, a "trial and error" procedure is typically followed in the design office to decide on the most appropriate design scheme in the number and location of the bearing systems; the latter typically based on engineering judgment to balance performance with cost. To this end, the particular research effort aims to develop a decision-making system for the optimal preliminary design of seismically isolated bridges, assumed to respond as single degree of freedom (SDOF) systems. The proposed decision-making process is based on the current design provisions of Eurocode 8, but is complemented by additional criteria set according to expert judgment, laboratory testing and recent research findings, while using a combined cost/performance criterion to select from a database of bearings available on the international market. Software is also developed for the implementation of the system. The paper concludes with the application, and essentially the validation of the methodology and software developed through more rigorous MDOF numerical analysis for the case of a real bridge. © Springer Science+Business Media B.V. 2011
