Recommendations for the Fatigue Design of Steel Structures
Recommendations for the Fatigue Design of Steel Structures (No: 043)
ECCS - Technical Committee 6 - Fatigue
These Recommendations provide a model code foe the assessment, fabrication, inspection and maintenance of steel structures subjected to fatigue loading. The procedures assume that the structure has been designed in accordance with the other limit state requirements. Work on the Recommendations began with the first meeting of Technical Committee 6 "Fatigue" on April 20, 1979, in Lausanne. At that time, a working document had been prepared by the former F.CCS Committee 9 "Welded Joints", under the chairmanship of Dr. Wallin. During a five year period, nine committee meetings were held and six drafts, including the final draft were prepared. Many experts in the field devoted much time and effort to the preparation of the various drafts. For example, Mr. John Dibley spent a few weeks in Lausanne working on the early versions. Also, Prof. John Fisher and Dr. Tim Gurney gave the Committee the benefit of their many years of experience through several formal and informal discussions. The advice of such experts greatly improved the quality of the Recommendations.

Assessment of Existing Steel Structures: Recommendations for Estimation of Remaining Fatigue Life
Assessment of Existing Steel Structures: Recommendations for Estimation of Remaining Fatigue Life

This report is part of the so-called background documents on Eurocodes. It has been prepared to
provide technical insight on the way existing steel structures could be assessed and the remaining
fatigue life could be estimated.
It may be used as a main source of support to:
– further harmonize design rules across different materials, and
– further develop the Eurocodes.
Due to the demand for freight volume on rail and road, traffic has increased significantly in the past years leading to increasing number of heavy vehicles in the traffic flows and greater exploitation of their loading capacities. Because of environmental considerations there is also a tendency to further enhance the admissible loads in the design of new heavy vehicles (e.g. by increasing axle loads or using road trains). This all may affect the safety, serviceability and durability of existing bridges. Bridge authorities are therefore interested in agreed methods to assess the safety and durability of existing bridges and to make appropriate provisions for more refined maintenance methods, possible restriction of traffic, bridge-rehabilitation or substitution of old bridges by new ones where necessary. For steel bridges including the old riveted ones there are numerous approaches to such assessments, partly standardized by national codes or recommendations. In the light of the development of the European single market for construction works and engineering services there is thus a need to harmonize them and to develop agreed European technical recommendations for the safety and durability assessment of existing structures. These recommendations should follow the principles and application rules in the Eurocodes and provide a scheme with different levels of analysis: a basic level with general methods and further levels with higher sophistication that call for specific expertise.

C for Engineers and Scientists: An Introduction to Programming With ANSI C
Gary J. Bronson, Howard Silver, "C for Engineers and Scientists: An Introduction to Programming With ANSI C "
West Publishing Company | 1993 | ISBN: 0314008160 | 643 pages | PDF | 25,4 MB
This text introduces the C programming language using a range of engineering and science applications in the examples and exercises. The book assumes no programming experience and is suitable for an introduction to programming course (using C instead of Fortran or Pascal). Structured programming principles are introduced early and used throughout. Clear explanations and many example programs (using ANSI C) show C as a powerful tool in engineering and science applications. Includes exercises after each section, common programming error sections, and chapter summaries.

Title: Effects of Transverse Reinforcement and Bonded length on the Side-Blowout Capacity of Headed Reinforcement Author(s): R. A. DeVries, J. O. Jirsa and T. Bashandy Publication: Special Publication Volume: 180 Pages: 367-390 Keywords: Anchorage; bonding; reinforced concrete; slip; transverse reinforcement Date: October 1, 1998
Abstract:
Pullout tests were conducted on deeply embedded headed reinforcement to determine the effect of transverse reinforcement and bonded length on the side-blowout capacity and load-slip behavior of the anchorage. It was found that transverse ties or stirrups in the anchorage zone had little effect on the ultimate capacity. Increases in anchorage capacity were only observed when the head was positively anchored in contact behind a large crossing bar. Transverse reinforcement also had little effect on the load-slip behavior before failure. However, when large amounts of transverse reinforcement were placed near the head, the amount of load maintained after the blowout failure occurred was increased. Additional bonded length of a deformed reinforcing bar increased the anchorage capacity and reduced the head slip for a given load. The amount of increase in capacity can be predicted using current ACI provisions for development length. Design procedures taking into account the effects of transverse reinforcement and bonded length were developed.
