WinRAR 3.91 beta 2 Multilingual Portable
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 particularly well.
WinRAR benefits
• 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.
• When you purchase WinRAR license you are buying a license to the complete technology, no need to purchase add-ons to create self-extracting files, it's all included.
• 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.
WinRAR 3.91 Beta 2
1. WinRAR might crash when testing corrupt CAB files.
2. Beta 1 crashed on some of TAR.BZ2 archives.
3. Total progress bar could be displayed incorrectly in "Convert archives" command in beta 1.
4. SFX archives set the wrong value to "sfxcmd" environment variabe if user account control prompt was displayed when unpacking.

A response spectrum method for random vibrations
Der Kiureghian, Armen
UCB/EERC-80/15, Earthquake Engineering Research Center, University of California, Berkeley, 1980-06, 46 pages (575/D44/1980)
A response spectrum method for stationary random vibration analysis of linear structures is developed. The method is based on the assumption that the input excitation is a wide-band, stationary Gaussian process and that the response is also stationary. However, the method can also be used as a good approximation for the response to a transient stationary Gaussian input with a duration several times longer than the fundamental period of the structure. Various response quantities, including the mean-squares of the response and its time derivative, the response mean frequency, and the cumulative distribution and the mean and variance of the peak response, are obtained in terms of the ordinates of the mean response spectrum of the input excitation and the modal properties of the structure. The formulation includes the cross correlation between modal responses, which are shown to be significant for modes with closely spaced natural frequencies. The proposed procedure is demonstrated for an example structure that is subjected to earthquake-induced base excitations. Computed results based on the response spectrum method are in close agreement with simulation results obtained from time-history dynamic analysis. The significance of closely spaced modes and the error associated with a conventional method that neglects the modal correlations are also demonstrated through this example.

Best Practice in Steel Construction - Residential Buildings
This publication presents best practice for the design of steel construction
technologies used in residential buildings, and is aimed at architects and other
members of the design team in the early stages of planning a residential
building project. It was prepared as one of a series of three under an RFCS
dissemination project Euro-Build in Steel (Project n° RFS2-CT-2007-00029).
The project’s objective is to present design information on best practice in steel,
and to take a forward look at the next generation of steel buildings. The other
publications cover best design practice in commercial and residential buildings.
