Download or read book Manual for Repair and Retrofit of Fatigue Cracks in Steel Bridges written by and published by . This book was released on 2013 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual is a synthesis of published literature as well as the collective experience gathered from participants of a workshop held at Lehigh University August 14-15, 2002 [herein referred to as the Fatigue Workshop]. It presents what are the consensus best practices for repair and retrofit of fatigue cracks in steel bridges as of 2010. The manual is also a guide for owners and consulting engineers to use for design and detailing of repairs and retrofits for fatigue cracks. It should be used in conjunction with existing specifications, codes, and engineering judgment. In addition to designing and executing the repairs and/or retrofits, there are numerous other steps involved in the inspection and assessment of a cracked bridge member. Detailed discussion of inspection and fatigue and fracture assessment are beyond the scope of this manual and, therefore, are only briefly discussed below with reference to other documents.

This book was released on 2009-06-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brittle fracture of the Hoan Bridge in December 2000 highlighted the fracture susceptibility of details containing intersecting welds in steel bridges. Though it is now known that details with intersecting welds should be avoided, many existing bridges in Indiana contain details with intersecting welds. Little experimental data on the fatigue performance of these details exists. The purpose of this study was to evaluate the fatigue strength of several details commonly found in steel bridges in Indiana that contain intersecting welds. Large-scale experimental fatigue testing were performed using nine steel beams to study the behavior of three basic types of welded details: a vertical stiffener, a horizontal stiffener terminating near a vertical stiffener, and a horizontal gusset plate coped to fit around a vertical stiffener. The welded details in this study were fabricated with varying degrees of web gap, defined as the distance between perpendicular weld toes. The results of the experimental testing were examined and compared to prior testing to determine if the size of the web gap affected the fatigue strength. Furthermore, the performance of drilled hole retrofits used to extend the fatigue life of these details was studied. Within the scope of the fatigue testing program, the presence of intersecting welds was not found to significantly affect the fatigue strength of vertical stiffener and horizontal gusset details. However, the size of the web gap may have had an effect on the fatigue strength of details where a horizontal stiffener terminated near a vertical stiffener. Further experimental testing is needed to more clearly define the relationship between web gap and fatigue strength for this case. Drilled hole retrofits were successful at prolonging the lives of these details to varying degrees, but it should be noted that the stress redistribution resulting from these holes may cause fatigue cracking at nearby weld toes.

This book was released on 2005 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 354: Inspection and Management of Bridges with Fracture-Critical Details explores the inspection and maintenance of bridges with fracture-critical members (FCMs), as defined in the American Association of State Highway and Transportation Officials' Load and Resistance Factor Design (LRFD) Bridge Design Specifications. The report identifies gaps in literature related to the subject; determines practices and problems with how bridge owners define, identify, document, inspect, and manage bridges with fracture-critical details; and identifies specific research needs. Among the areas examined in the report are inspection frequencies and procedures; methods for calculating remaining fatigue life; qualification, availability, and training of inspectors; cost of inspection programs; instances where inspection programs prevented failures; retrofit techniques; fabrication methods and inspections; and experience with fracture-critical members fractures and problems details.
