The study of structural instability plays a role of primary importance in the field of applied mechanics. Despite the remarkable progresses made in the recent past years, the structural instability remains one of the most challenging topics in applied - chanics. Many problems have bee:: solved in the last decades but still many others remain to be solved satisfactorily. The increasing number of papers published in jo- nals and conferences organized by ECCS, SSRC, IUTAM, and EUROMECH strongly indicates the interest of scientists and engineers in the subject. A careful examination of these publications shows that they tend to fall into one of the two categories. The first is that of practical design direction in which methods for analyzing specific stability problems related to some specific structural typologies are developed. The research works are restricted to determining the critical load, considering that it is sufficient to know the limits of stability range. These studies are invaluable since their aim is to provide solutions to practical problems, to supply the designer with data useful for design and prepare norms, specifications and codes. The second direction is that of theoretical studies, aiming at a mathematical modeling of the instability problems, for a better understanding of the phenomena. In these studies, special emphasis is placed on the behavior of structures after the loss of stability in the post-critical range. This approach is less familiar to designers as its results have not yet become part of current structural design practice.

WinRAR is a powerful archive manager. RAR files can usually compress content by 8 percent to 15 percent more than ZIP files can. WinRAR is a powerful compression tool with many integrated additional functions to help you organize your compressed archives. It can backup your data and reduce size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format.
WinRAR puts you ahead of the crowd when it comes to compression. By consistently creating smaller archives, WinRAR is often faster than the competition. This will save you disc space, transmission costs AND valuable working time as well. WinRAR is ideal for multimedia files. WinRAR automatically recognizes and selects the best compression method. The special compression algorithm compresses multimedia files, executables and object libraries
Features of WinRAR:
- Using WinRAR puts you ahead of the crowd when it comes to compression by consistently making smaller archives than the competition, saving disk space and transmission costs.
- WinRAR provides complete support for RAR and ZIP archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z archives.
- WinRAR offers a graphic interactive interface utilizing mouse and menus as well as the command line interface.
- WinRAR is easier to use than many other archivers with the inclusion of a special "Wizard" mode which allows instant access to the basic archiving functions through a simple question and answer procedure. This avoids confusion in the early stages of use.
- WinRAR offers you the benefit of industry strength archive encryption using AES (Advanced Encryption Standard) with a key of 128 bits.
- WinRAR supports files and archives up to 8,589 billion gigabytes in size. The number of archived files is, for all practical purposes, unlimited.
- WinRAR offers the ability to create selfextracting and multivolume archives.
Recovery record and recovery volumes allow to reconstruct even physically damaged archives.
- WinRAR features are constantly being developed to keep WinRAR ahead of the pack.
New Features:
1. WinRAR can unpack TAR archives containing folders with pax extended headers. Previous versions failed to unpack them.
2. "Keep broken files" extraction option is supported for 7-Zip archives.
3. Bugs fixed:
a) WinRAR 5.10 did not set "hidden", "read-only" and "system" file attributes when unpacking ZIP archives;
b) WinRAR 5.10 failed to update self-extracting RAR archives containing nested ZIP archives stored without compression;
c) ZIP archive created with "Do not store paths" option included unnecessary empty name records for folders;
d) archived files could have 1 hour modification time error in Windows XP;
e) deleting a file in RAR5 solid archive containing files stored with -ver switch caused such files to lose version information;
f) black rectangles were displayed instead of toolbar buttons in 16- and 24- bit screen color modes and Windows custom text size larger than 100%

Private Note:
The archives are self-extracting. That's why the file extensions are EXE.

This specification is a Reference Specification that the Architect/Engineer can make applicable to a construction project by citing it in the Project Specifications. The Architect/Engineer supplements the provisions of this Reference Specification as needed by designating or specifying individual project requirements. The document covers materials and proportioning of concrete; reinforcement and prestressing reinforcement; production, placing, finishing, and curing of concrete; formwork design and construction; and shotcrete. Methods of treatment of joints and embedded items, repair of surface defects, and finishing of formed and unformed surfaces are specified. Separate sections are devoted to architectural concrete, mass concrete, and internal and external post-tensioned prestressed concrete. Provisions governing testing, evaluation, and acceptance of concrete as well as acceptance of the structure are included.
