The GGU-VIBRATION program system facilitates the analysis of vibrations in structures after Achmus, Kaiser and tom Wörden ('Bauwerkserschütterungen durch Tiefbauarbeiten' in Bulletin 61, IGBE, Hannover University). Example 1 (vibration roller) and Example 2 (driving ram (diesel hammer)) from Prof. Achmus' article are provided as files.
The theoretical principles are included in Bulletin 61 (IGBE, Hannover University). They will therefore only be repeated for this manual as far as necessary to describe the input.
The program includes convenient data input. The system is permanently displayed on the screen. Every change to the data is displayed on the screen, so that optimum control of the input data is guaranteed.There are "?" and "Info"’ buttons in the dialog boxes for many technical and program-specific questions. Click on the "?" buttons or "Info" buttons to obtain the necessary information.
The graphic output supports the true type fonts provided by WINDOWS, so that an excellent layout is guaranteed. Colour output and numerous graphic formats (BMP, TIF, JPG etc.) are supported. PDF and DXF files can also be imported via the integrated Mini-CAD system (see "Mini-CAD" manual).
The program has been extensively tested. No errors have been found. Nevertheless, liability for completeness and correctness of the program and the manual, and for any damage resulting from incompleteness or incorrectness, cannot be accepted.
