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.

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 work was commissioned by the Highways Agency to produce guidance for bridge designers by addressing the thermally induced soil/structure integration problem created by environmental changes of temperature and the associated cyclical displacements imposed on the granular backfill to the bridge abutments. It develops a better theoretical understanding of the cyclic performance, in particular the strain racheting in the backfill soil when in contact with a stiff structure. It also identifies the governing soil parameters and examines their influence in the interaction problem, develops numerical modelling procedures to predict interactive soil behaviour, and identifies and quantifies the controlling features of bridge structures relevant to the interaction problem.

This is a state-of-the-art reference, an exchange of innovative experience, creative thinking and industry forecasts. This volume presents the proceedings of the fourth international conference in this series based in the Asia Pacific region, in Kuala Lumpur in October 2005 and is applicable to all sectors of the bridge engineering community. BACKGROUND KNOWLEDGE AND FUTURE PERFORMANCE The Institution of Civil Engineers has collaborated with internationally renowned bridge engineers to organise three successful conferences to celebrate the enormous achievements made in the field of bridge engineering in recent years. As a discipline, bridge engineering not only requires knowledge and experience of bridge design and construction techniques but must also deal with increasing challenges posed by the need to maintain the long-term performance of structures throughout an extended service life. In many parts of the world natural phenomena such as seismic events can cause significant damage to force major repairs or reconstruction. Therefore, it is appropriate that the first plenary session of this conference is entitled Engineering for Seismic Performance. READERSHIP This compilation of papers will benefit practising civil and structural engineers in consulting firms and government agencies, bridge contractors, research institutes, universities and colleges. In short, it is of importance to all engineers involved in any aspect of the design, construction and repair, maintenance and refurbishment of bridges.

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.

Integral Bridges (IBs) are joint-less bridges whereby the deck is continuous and monolithic with abutment walls. IBs are outperforming their non-integral counterparts in economy and safety. Their principal advantages are derived from the absence of expansion joints and sliding bearings in the deck, making them the most cost-effective system in terms of construction, maintenance, and longevity. The main purpose of constructing IBs is to prevent the corrosion of structure due to water seepage through joints. The simple and rapid construction provides smooth, uninterrupted deck that is aesthetically pleasing and safer for riding. The single structural unit increases the degree of redundancy enabling higher resistance to extreme events. However, the design of IBs not being an exact science poses certain critical issues. The continuity achieved by this construction results in thermally induced deformations. These in turn introduce a significantly complex and nonlinear soil-structure interaction into the response of abutment walls and piles of the lB. The unknown soil response and its effect on the stresses in the bridge, creates uncertainties in the design. To gain a better understanding of the mechanism of load transfer due to thermal expansion, which is also dependent on the type of the soil adjacent to the abutment walls and piles, a 3D finite element analysis is carried out on a representative IB using state-of-the-art finite element code ABAQUS/Standard 6.5-1. A literature review focusing on past numerical studies of IBs is presented, followed by details of the numerical model developed in this study using the interactive environment ABAQUS/CAE 6.5-1 along with the analysis details. A discussion of results of the analysis of the IB with three different soil conditions, each experiencing three different temperature change scenarios is presented. Conclusions of the study and recommendations for future research wrap up the report. The advancement of knowledge enabled by this research will provide a basis for introduction of new guidelines in Kansas Bridge Design Manual.

Worldwide, integral type bridges are being used in greater numbers in lieu of jointed bridges because of their structural simplicity, first-cost economy, and outstanding durability. In the UK and the US states of Tennessee and Missouri, for example, the construction of most moderate length bridges is based on the integral bridge concept. The state of Washington uses semi-integral bridges almost exclusively, while, depending on subfoundation characteristics, the state of Ohio and others use a mix of these two bridge types. Integral and Semi-Integral Bridges has been written by a practicing bridge design engineer who has spent his entire career involved in the origination, evaluation and design of such bridges in the USA, where they have been in use since the late 1930’s. This work shows how the analytical complexity due to the elimination of movable joints can be minimized to negligible levels so that most moderate length bridges can be easily and quickly modified or replaced with either integral or semi-integral bridges. Bridge design, construction, and maintenance engineers; bridge design administrators; graduate level engineering students and structural research professionals will all find this book exceptionally informative for a wide range of highway bridge applications.
