Evaluation of steel bridges

Written in English
This report is divided into two volumes. Volume I summarizes a structural health monitoring (SHM) system that was developed for the Iowa DOT to remotely and continuously monitor fatigue critical bridges (FCB) to aid in the detection of crack formation. The developed FCB SHM system enables bridge owners to remotely monitor FCB for gradual or sudden damage formation. The SHM system utilizes fiber bragg grating (FBG) fiber optic sensors (FOSs) to measure strains at critical locations. The strain-based SHM system is trained with measured performance data to identify typical bridge response when subjected to ambient traffic loads, and the knowledge is used to evaluate newly collected data. At specified intervals, the SHM system autonomously generates evaluation reports that summarize the current behavior of the bridge. The evaluation reports are collected and distributed to the bridge owner for interpretation and decision making. This volume (Volume II) summarizes the development and demonstration of an autonomous, continuous SHM system that can be used to monitor typical girder bridges. The developed SHM system can be grouped into two main categories: an office component and a field component. The office component is a structural analysis software program that can be used to generate thresholds which are used for identifying isolated events. The field component includes hardware and field monitoring software which performs data processing and evaluation. The hardware system consists of sensors, data acquisition equipment, and a communication system backbone. The field monitoring software has been developed such that, once started, it will operate autonomously with minimal user interaction. In general, the SHM system features two key uses. First, the system can be integrated into an active bridge management system that tracks usage and structural changes. Second, the system helps owners to identify damage and deterioration.

Starting with a study of the evolution in the design of steel bridges and lessons learnt from some landmark bridge failures, the book discusses basic topics, such as design philosophies, characteristics of steel and loads, before dealing with the various structural arrangements commonly used in modern steel bridges and their selection strategies. Mistry: High Performance Steel For Highway Bridges Published by ECI Digital Archives, Figure 1: CVN Transition Curve 8. STEEL SPECIFICATIONS High performance Steel is a quenched and tempered plate product available in thickness to 4 inches for use in bridges. It conforms to ASTM A/AM specification requirements.
The book contains several chapters explaining important aspects of fabrication and erection, including methodologies for erection of common steel bridges. Durability, protection against corrosion and post-construction maintenance are discussed in by: 2.

Evaluation, repair and rehabilitation of bridges are increasingly important topics in the effort to deal with the deteriorating infrastructure. For example, in the United States about 40 percent of the nation's , bridges are classified, according to the Federal Highway Administra tion's (FHW A) criteria, as deficient and in need of.

Weiwei Lin, Teruhiko Yoda, in Bridge Engineering, Introduction. Steel bridges are widely used around the world in different structural forms with different span length, such as highway bridges, railway bridges, and footbridges.
The main advantages of structural steel over other construction materials are its strength, ductility, easy fabrication, and rapid construction. Evaluation of Steel Bridges Using In-Service Testing MICHEL GHOSN, FRED MOSES, and JOHN GOBIESKI ABSTRACT Highway bridges often exhibit higher strengths than indicated by AASHTO rating procedures.
This is because the code is inherently conservative and. PDF files can be viewed with the Acrobat® Reader®. This document is a technical summary of the Federal Highway Administration report, Performance Evaluation of One-Coat Systems on New Steel Bridges (FHWA-HRT).
