Book excerpt: Integral abutment bridges have been used in the United States for decades. By eliminating expensive expansion joints, the piles supporting the end bent accommodate the total thermal movement of the bridge. Currently, integral bridges are designed based upon experience, and a rational design specification has not been developed. Furthermore, the interaction of the abutment, pile, and soil remains uncertain. A better understanding regarding the behavior of this system is needed. The objective of this research is to evaluate the behavior of the integral abutment-pile system and evaluate any limitations of its use. To achieve this objective, two phases of research were conducted. The first phase was a field study that investigated the in-service pile behavior of four integral abutment bridges. The second phase was an experimental study that was used to evaluate the capability of piles typically used in integral abutment bridges. Nine low-cycle, large amplitude lateral displacement pile tests were conducted. Throughout both phases, analytical investigations were also conducted. To develop simplified modeling techniques that sufficiently account for soil-pile interaction, the piles supporting abutments were analytically modeled and calibrated based on the field and experimental results. A parametric study was also performed with variables including pile type, pile orientation, axial load, pile length, and soil type. The results of these phases were evaluated and design recommendations were developed based on these results. Overall, the design recommendations provide for an extension in the length limits often used for integral bridges. The extension of these limits can result in a reduction in bridge construction and maintenance costs for a large number of structures that cannot currently be built using this structural system.

This book was released on 2011-08-15 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integral abutment (IA) construction has become the preferred method over conventional construction for use with typical highway bridges. However, the use of these structures is limited due to state mandated length and skew limitations. To expand their applicability, studies were implemented to define limitations supported by rational analysis rather than simply engineering judgment. Previous research investigations have resulted in larger length limits and an overall better understanding of these structures. However, questions still remain regarding IA behavior; specifically questions regarding long-term behavior and effects of skew. To better define the behavior of these structures, a study was implemented to specifically investigate the long term behavior of IA bridges. First, a field monitoring program was implemented to observe and understand the in-service behavior of three integral abutment bridges. The results of the field investigation were used to develop and calibrate analytical models that adequately capture the long-term behavior. Second, a single-span, quarter-scale integral abutment bridge was constructed and tested to provide insight on the behavior of highly skewed structures. From the acquired knowledge from both the field and laboratory investigations, a parametric analysis was conducted to characterize the effects of a broad range of parameters on the behavior of integral abutment bridges. This study develops an improved understanding of the overall behavior of IA bridges. Based on the results of this study, modified length and skew limitations for integral abutment bridge are proposed. In addition, modeling recommendations and guidelines have been developed to aid designers and facilitate the increased use of integral abutment bridges.

This book was released on 2005 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Maine, there are often cases where the depth to bedrock prohibits integral abutments bridges from being used. The goal of this research is to determine the feasibility of constructing integral abutments in conditions that cannot provide the fixed support conditions that are traditionally assumed. A finite element model was created that incorporates realistic constitutive and surface interaction models.

Available in PDF, EPUB and Kindle. Book excerpt: Integral abutment bridges, a type of jointless bridge, are the construction option of choice when designing highway bridges in many parts of the country. Rather than providing an expansion joint to separate the substructure from the superstructure to account to volumetric strains, an integral abutment bridge is constructed so the superstructure and substructure are continuous. The abutment is supported by a single row of piles which must account for the longitudinal movement previously accommodated by the joints. The primary advantage of an integral abutment bridge is that it is jointless (expansion joints are eliminated) and thus reduces both upfront and overall life-cycle costs. In addition to other benefits provided by integral construction, the reduction in overall cost has led to INDOT requiring all new structures within certain geometric limitation be integral. These geometric limitations, traditionally based on engineering judgment, have been modified over time based as investigations have revealed more about the behavior of integral abutment bridges. While there has been a considerable amount of research and investigation conducted on the behavior of integral abutment bridges, information is limited on both long-term behavior and the effects of highly skewed structures. Because there is a great desire for the application of these structures to be expanded, this research serves to expand the understanding of the behavior of integral abutment structures. Additionally, updated geometric limitations are recommended along with design recommendations and recommended analysis procedures for properly modeling integral abutment behavior.

Available in PDF, EPUB and Kindle. Book excerpt: Worldwide, integral type bridges are being used in greater numbersin lieu of jointed bridges because of their structural simplicity,first-cost economy, and outstanding durability. In the UK and theUS states of Tennessee and Missouri, for example, the constructionof most moderate length bridges is based on the integral bridgeconcept. The state of Washington uses semi-integral bridges almostexclusively, while, depending on subfoundation characteristics, thestate of Ohio and others use a mix of these two bridge types. Integral and Semi-Integral Bridges has been written by apracticing bridge design engineer who has spent his entire careerinvolved in the origination, evaluation and design of such bridgesin the USA, where they have been in use since the late1930’s. This work shows how the analytical complexity due tothe elimination of movable joints can be minimized to negligiblelevels so that most moderate length bridges can be easily andquickly modified or replaced with either integral or semi-integralbridges. Bridge design, construction, and maintenance engineers; bridgedesign administrators; graduate level engineering students andstructural research professionals will all find this bookexceptionally informative for a wide range of highway bridgeapplications.

Book excerpt: The objectives of this research program were to evaluate the state-of-art for the design of prestressed-concrete (PC), integralabutment bridges; to validate the assumptions that are incorporated in the current-design procedures for these types of bridges when they are subjected to thermal-loading conditions; and, as appropriate, to revise and improve the current-design procedures for this type of a bridge, as that design relates to the thermally-induced displacements of the abutments and the thermally-induced forces in the abutments and abutment piles. Two, skewed, PC girder, integral-abutment bridges in the State of Iowa were instrumented over a two-year period to measure structural behavior. Longitudinal and transverse displacements and rotation of the integral abutments, strains in the steel piles and in the PC girders, and temperature distributions were recorded throughout the monitoring period for both bridges. The coefficient of thermal expansion and contraction for the concrete in core specimens that were taken from 20 bridge decks and from several PC girders was experimentally measured at the 100%-dry and 100%-saturated conditions. The longitudinal displacements of the integral abutments correlated well with the recorded change in the bridge temperature. Total, longitudinal, pile strains exceeded the minimum, specified, yield strain of the steel for both bridges. Longitudinal strains in the PC girders were well within acceptable limits. The experimental data were used to calibrate and refine finite-element models of both bridges. Discrepancies were not fully explained for the differences between the predicted and measured, thermal expansion of the bridge and vertical rotations of the integral abutments.
