However, one of the limitations of SHAKE91 is the lack of a user-friendly interface for creation of the input files, and for the processing of the output data. To this end, we have developed ShakEdit, a Windows 3.1 based editor for SHAKE91. In a typical application, ShakEdit is used to create an input file for SHAKE91. User-friendly screens are provided to input the data for the different SHAKE91 options, and then to create an input file. After running SHAKE91 in a DOS window, ShakEdit is used to process the output files generated, resulting in the creation of a series of files containing acceleration and/or stress/strain time history data, response and amplification spectrum data, strain-compatible soil properties, peak acceleration, maximum shear stress, etc.. The results can also be viewed graphically in ShakEdit, and the graphics created can be saved/printed for inclusion in documents. Additional features of ShakEdit include: - A number of Attenuation Relationships for peak horizontal acceleration and velocity with distance; and, for the pseudo acceleration or pseudo velocity response spectrum. - Design spectra such as NEHRP and AASHTO. These spectra and those from attenuation relationships can be plotted simultaneously with the spectra computed with SHAKE91. - Computation of cyclic stress ratio (CSR) based on equivalent uniform shear stress using the shear stresses computed with SHAKE91;and, estimation of the cyclic stress ratio required to initiate liquefaction using standard penetration test results and the CSR vs (N1)60 chart developed by Seed et al. (1985). - On-line help for most editing and graphing operations. A trial version of the program can be downloaded from: http://www.winsite.com/info/pc/win3/demo/shakedit.zip/ This trial version has some bugs that were reported after I uploaded the program. I have fixed most of these bugs in the new version, and added a couple of new functions. The updated version will be available for downloading in a few days. The cost of ShakEdit is $65.00, plus $10.00 for shipping and handling, for the first copy. Additional copies are $25.00. SHAKE91 is not included with ShakEdit.
