Book Description
According to the National Bridge Inventory, the most common type of short-to-medium span highway bridge in the US is the reinforced concrete (RC) slab-on-steel girder bridge with RC abutments and piers, comprising approximately half of Ohio's inventory. For these bridges AASHTO currently offers a number of rating methods each of which is based solely on theoretical and design calculations. These methods are known to result in subjective/conservative ratings, not calibrated against field measurements, and hence possibly not objectively reflecting the realities and impacts of individual bridge condition as well as design details. Visual inspections provide at best qualitative and subjective information on bridge condition which is hard to incorporate into the rating process. One result of this approach is the potentially inefficient management and maintenance practices based on conservative/subjective ratings and inspection reports. In addition, there is the need to understand the true impact design and construction practices have on serviceability and safety of the bridge inventory, something which cannot be explored based on the current approaches.

Book Description
Premature deterioration and structural deficiencies plague highway bridges throughout the United States. Over 40% of the nation's bridges are currently classified as structural and/or traffic liabilities. Subjective evaluation of visual data does not appear to provide the necessary information to properly identify deficient structures or to evaluate the validity of subsequent rehabilitation or repair. The development of practical, effective, and reliable inspection/ condition assessment techniques depends on the availability of objective data acquired through on-site, nondestructive field tests. The primary objective of this research has been to rigorously demonstrate that modal analysis and the measure of flexibility extracted from modal test data are effective tools for the condition assessment of structures. Modal test methods and modal flexibility were utilized on a decommissioned 3 span steel girder/concrete deck overpass in Cincinnati, Ohio. The bridge was subjected to various controlled damage and retrofit scenarios such as: Removal of expansion joints and bumper angles at abutments, removal and restoration of a sliding bearing, incremental cuts along a girder bottom flange, web cuts in several stages, cross frame cuts and a deck delamination.

Book Description
Comprising 102 papers presented by researchers from all over the world, the proceedings of this workshop contain current information about a variety of structural health monitoring technologies, as well as their current and potential applications in various fields. Emphasis is placed on those technologies that are promising for future applications in industry and government and the infrastructures that are needed to support such technological development. The content of the workshop is divided into keynote presentations (ten altogether), aerospace applications, general applications, civil applications, integration and systems, sensors, and signal processing and diagnostic methods. Includes the editor's summary report on the results of the panel discussions and presentations from the First International Workshop on Structural Health Monitoring held at Stanford U. in September 1997.

Book Description
These proceedings are from The Fourth International Conference on Bridge Management that consolidated the best and, more importantly, up-to-date research conducted in the field of bridge management. Since the first conference in 1990 the scientific art of bridge management has advanced at an astonishing rate. There has been a change from a curative to a preventative approach to bridge management, promising an increased longevity for the next generation of bridges and reduced whole-life costs, and practical and economical solutions have been found for some recurring problems.

Book Description
The stresses imposed on UK roads by forty tonne vehicles have led to an extensive programme of bridge improvements across the country. This book draws on case studies to create an essential tool for all bridge engineers involved in strengthening steel bridges to meet these challenges.Resulting from the Highways Agency's assessment and strengthening of steel and steel/concrete composite bridges, this report disseminates the knowledge gained and ingenuity used during this work and will be an invaluable reference for future work.

Book Description
Indeed, this essential working reference for practicing civil engineers uniquely reflects today's gradual transition from allowable stress design to Load and Resistance Factor Design by presenting LRFD specifications - developed from research requested by AASH-TO and initiated by the NCHRP - which spell out new provisions in areas ranging from load models and load factors to bridge substructure elements and foundations.
