"This book focuses on micro-corrugation on metal, mostly thin sheets. While tools have been developed just for this purpose, more common tools are crimpers used to extract the last squeeze from a tube or a category of tools used in paper craft. When applied to sheet metal the result is a wavy panel with parallel crests and troughs. This makes an appealing pattern and can be used as is."--Publisher.

New expanded second edition with key technical, regulatory and marketing developments from the past 10 years in the packaging industryCovers the materials, processes, and design of virtually all paper and fiberboard packaging for end-products, displays, storage and distributionNew information on European and global standards, selection criteria for paperboard, as well as emerging sustainability initiativesExplains recent tests, measurements and costs with ready-to-use calculations Ten years ago, the first edition of Cartons, Crates and Corrugated Board quickly became the standard reference book for wood- and paper-based packaging. Endorsed by TAPPI and other professional societies and used as a textbook worldwide, the book has now been extensively revised and updated by a team formed by the original authors and two additional authors. While preserving the critical performance and design data of the previous edition, this second expanded edition offers new information on the technologies, tests and regulations impacting the paper and corrugated industries worldwide, with a special focus on Europe and Japan. New information has been added on tests and novel designs for folded cartons, as well as expanded discussions of paperboard selection for specific applications, emerging barrier packaging, food contact and migration, and the dynamics and opportunities of corrugated in distribution systems. Recent developments on recycling and sustainability are also highlighted.

ICSSD 2002 is the second in the series of International Conferences on Structural Stability and Dynamics, which provides a forum for the exchange of ideas and experiences in structural stability and dynamics among academics, engineers, scientists and applied mathematicians. Held in the modern and vibrant city of Singapore, ICSSD 2002 provides a peep at the areas which experts on structural stability and dynamics will be occupied with in the near future. From the technical sessions, it is evident that well-known structural stability and dynamic theories and the computational tools have evolved to an even more advanced stage. Many delegates from diverse lands have contributed to the ICSSD 2002 proceedings, along with the participation of colleagues from the First Asian Workshop on Meshfree Methods and the International Workshop on Recent Advances in Experiments and Computations on Modeling of Heterogeneous Systems. Forming a valuable source for future reference, the proceedings contain 153 papers ? including 3 keynote papers and 23 invited papers ? contributed by authors from all over the world who are working in advanced multi-disciplinary areas of research in engineering. All these papers are peer-reviewed, with excellent quality, and cover the topics of structural stability, structural dynamics, computational methods, wave propagation, nonlinear analysis, failure analysis, inverse problems, non-destructive evaluation, smart materials and structures, vibration control and seismic responses.The major features of the book are summarized as follows: a total of 153 papers are included with many of them presenting fresh ideas and new areas of research; all papers have been peer-reviewed and are grouped into sections for easy reference; wide coverage of research areas is provided and yet there is good linkage with the central topic of structural stability and dynamics; the methods discussed include those that are theoretical, analytical, computational, artificial, evolutional and experimental; the applications range from civil to mechanical to geo-mechanical engineering, and even to bioengineering.

To date, very little has been published on the topic of corrugated-steel-web bridges. fib Bulletin 77 offers the global engineering community a first complete overview of this fascinating technology. The shear capacity of corrugated-steel web began to be studied in Japan in 1965 and resulted in the use of corrugated steel in steel-girder webs as a replacement for web stiffeners. After Japan laid the groundwork for the technology, France built the first composite bridge with corrugated-steel webs and upper and lower concrete slabs in the 1980s. Composite bridges had already been popular in France but engineers found that concrete slab creep meant that prestressing force spread into the steel plates, causing high losses. Corrugated-steel web, which reduces axial stiffness, was welcomed as a solution to this problem and several bridges were designed and built with this technology. Building on France’s composite technology, Japan began developing corrugated-web precast box-girder bridges in the 1990s and today has over 140 corrugated-web bridges, by far the largest number for any country in the world. Japanese engineers have come a long way in solving issues such as fatigue and ultimate load behaviour and have made good use of corrugated-steel web’s advantages for bridge building, which include reduced self weight (of approximately 15% compared with the weight of an ordinary concrete box-girder bridge), economy and improved construction processes. fib Bulletin 77: Corrugated-steel-web bridges covers numerous examples of bridges in Japan and France as well as an in-depth case study and analysis of a large corrugated-steel-web bridge in Germany. This publication offers designers, proprietors, contractors and architects alike relevant technical and theoretical information on construction processes along with ideas for future development.

Optimum corrosion protection of post-tensioning tendons has been a priority since the beginning of this technology. The temporary ban of grouted post-tensioning tendons in the United Kingdom, from 1992-1996, has initiated a review of all aspects related to durability of post-tensioning tendons. One of the UK conclusions of this review was to require encapsulation of the post-tensioning tendons into wear-resistant and leak-tight plastic ducts to serve as an additional corrosion protection barrier. Since that time, other countries have at least partially adopted similar approaches. Designs of these plastic ducts may vary significantly between different suppliers. In addition, experience with these systems is still relatively limited. Hence, these plastic ducts cannot be standardised at this time. Therefore, the former FIP Commission 2, and now fib Commission 9 Reinforcing and Prestressing Materials and Systems, has set-up a task group to prepare a fib report on corrugated plastic ducts for internal, bonded post-tensioning. This report is written as a guide for an approval process for such plastic ducts. It shall serve readers such as authorities, and engineers as a guide on how to set-up a formal state approval process for these ducts, or at least allow them to properly assess systems offered for a specific project.
