This book contains the invited contributions to the 1993 Henderson Colloquium organised by the British Group of IABSE (International Association for Bridge and Structural Engineering). It provides an international review of new techniques of designing and constructing joint-free bridges - an approach which is rapidly being developed and used in many parts of the world.

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.

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.

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.

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.
