Just out of curiosity, can you tell me what value of Young's module of elasticity (E, or less commonly Y) do you associate to reinforcement marked as RA400/500 and which to one marked as B500B?
What value of E do you put in your calculations a/o softwares?
Regards,
Grunf
(Maybe not all of you heard or used RA400/500, so I'll just say that's an old class of reinforcement used in Croatia (maybe someplace else, I don't know), now we use B500 (or now B500 should be used, as far as I know)

Author: Richard S. Figliola, Donald E. Beasley | Size: 4.3 MB | Format:PDF | Publisher: Wiley | Year: 2011 | pages: 605 | ISBN: 0470547413
The fifth edition of this market leading book provides mechanical engineers with the most up to date coverage of mechanical measurements. Sound theory is highlighted by rich and current practical examples. New chapter opening learning objectives and outcomes explore the critical concepts that will be discussed. New and revised examples and problems clearly show how the information is applied in the field. Expanded discussions are included on measurements, equipment, and basic metrology. The DFT concept presentation is now simplified. More pictures have also been added to make the material easier to learn. Mechanical engineers will then better understand the elements for the design of measurement systems and measurement test plans.

The field of corrosion science and engineering is on the threshold of important advances. Advances in lifetime prediction and technological solutions, as enabled by the convergence of experimental and computational length and timescales and powerful new modeling techniques, are allowing the development of rigorous, mechanistically based models from observations and physical laws.
Despite considerable progress in the integration of materials by design into engineering development of products, corrosion considerations are typically missing from such constructs. Similarly, condition monitoring and remaining life prediction (prognosis) do not at present incorporate corrosion factors. Great opportunities exist to use the framework of these materials design and engineering tools to stimulate corrosion research and development to achieve quantitative life prediction, to incorporate state-of-the-art sensing approaches into experimentation and materials architectures, and to introduce environmental degradation factors into these capabilities.
Research Opportunities in Corrosion Science and Engineering identifies grand challenges for the corrosion research community, highlights research opportunities in corrosion science and engineering, and posits a national strategy for corrosion research. It is a logical and necessary complement to the recently published book, Assessment of Corrosion Education, which emphasized that technical education must be supported by academic, industrial, and government research. Although the present report focuses on the government role, this emphasis does not diminish the role of industry or academia.

Architecture, which can be understood in its most basic sense as a form of enclosure created with an aesthetic intent, first made its appearance in the Prehistoric Age. From its earliest developments, architecture changed over time and in different cultures in response to changing cultural needs, aesthetic interests, materials, and techniques.
The A to Z of Architecture provides information on architects like Frank Lloyd Wright, Tadao Ando, Leon Battista Alberti, Filippo Brunelleschi, Michelangelo, and Konstantin Stepanovich Melnikov, as well as on famous structures like the Acropolis, the Colosseum, the Forbidden City, Machu Pichu, Notre Dame, the Pyramids of Giza, Stonehenge, and the World Trade Center. The dictionary examines the development of architecture over the centuries through a chronology, an introductory essay, a bibliography, and hundreds of cross-referenced dictionary entries on the major architects, well-known buildings, time periods, styles, building types, and materials in world architecture.

Vibration and structural acoustics analysis has become an essential requirement for high-quality structural and mechanical design in order to assure acoustic comfort and the integrity, reliability and fail-safe behavior of structures and machines. The underlying technologies of this field of multidisciplinary research are evolving very fast and their dissemination is usually scattered over different and complementary scientific and technical publication means. In order to make it easy for developers and technology end-users to follow the latest developments and news in the field, this book collects into a single volume selected, extended, updated and revised versions of papers presented at the Symposium on Vibration and Structural Acoustics Analysis, coordinated by J. Dias Rodrigues and C. M. A. Vasques, which was organised as part of the 3rd International Conference on Integrity, Reliability & Failure (IRF’2009), co-chaired by J. F. Silva Gomes and Shaker A. Meguid, held at the Faculty of Engineering of the University of Porto, Portugal, 20-24 July 2009. These papers where chosen from the more than 60 papers presented at the conference symposium. Written by experienced practitioners and researchers in the field, this book brings together recent developments in the field, spanning across a broad range of themes: vibration analysis, analytical and computational structural acoustics and vibration, material systems and technologies for noise and vibration control, vibration-based structural health monitoring/evaluation, machinery noise/vibration and diagnostics, experimental testing in vibration and structural acoustics, applications and case studies in structural acoustics and vibration. Each chapter presents and describes the state of the art, presents current research results and discusses the need for future developments in a particular aspect of vibration and structural acoustics analysis. The book is envisaged to be an appealing text for newcomers to the subject and a useful research study tool for advanced students and faculty members. Practitioners and researchers may also find this book a one-stop reference that addresses current and future challenges in this field. The variety of case studies is expected to stimulate a holistic view of sound and vibration and related fields and to appeal to a broad spectrum of engineers such as the ones in the mechanical, aeronautical, aerospace, civil and electrical communities.

This book reflects the practical experience the authors have gained in analyzing the box girder and the truss used in bridge engineering; the straight and curved box girder bridge, the truss bridge, and the arch-stiffened truss bridge are considered, whereby bending and torsional stresses, lateral buckling and vibrations are investigated. The authors have established a more accurate thin-walled beam theory of box girder, and, as an extension of the thin-walled beam theory, developed a theory of bending and torsion of the truss bridge. Many practical examples have been analyzed, and from these results, conclusions valuable to design practice have been deducted.

With an emphasis on hazard analysis, this volume assesses critical preparedness issues that emergency personnel must face in the event of a disaster of any kind. The author discusses the nature and consequences of such hazards and examines strategies at the individual, organization, community, and regional levels. He presents a systematic process for hazards identification, vulnerability determination, and consequence assessment for natural, built, and human environments. Covering every step, from planning and preparedness to mitigation, response, and recovery, the book provides information on hazard identification, modeling, loss estimation, risk perception and definition, and sustainability.

Practical design tools for unprotected steel columns submitted to ISO-Fire - Refao III
Size: 13.9 MB | Format:PDF | Publisher: COMMISSION OF THE EUROPEAN COMMUNITIES | Year: 1992 | pages: 342 | ISBN: 9282649385
The main parameters to be considered in this research programmer i.e. geometrical factors (shapes, buckling lengths), steel qualities and coefficients governing the heat exchanges are presented first. The temperature dependent stress-strain relationships of steel as initially existing in the program OEFIC0SS have been tested by simulation of bending tests described in the litterature. It has shown a necessity to improve these laws when pure steel elements have to be calculated. New improved stress-strain relationships of steel have been carried out and calibrated thanks to transient state beam tests performed on small simply supported steel beams, subjected to a concentrated constant load, and submitted to a controlled temperature increase. These new laws have been established as well for commonly used construction steels as for high strength steel FeE 460. The validity of these improved relationships has been next verified by simulating very well six full scale fire tests performed on unprotected steel columns in the laboratories of Braunschweig and Gent. The possibility to take into account a distribution of residual stresses has been introduced in CEFICOSS. The simulation of the six column tests showed that residual stresses have a quite small influence of the fire resistance time of columns. It has been decided, however, to consider systematically a distribution of residual stresses in the calculations. Practical design tools have been finally carried out and are proposed in form of tables as well as diagrams.
