NOTE ON EXCITATION OF LONG STRUCTURES BY GROUND WAVES

Engineering structures may experience vibrations excited by ground waves generated by earthquakes, explosions, or by other vibration sources. Dynamic models to analyze such vibrations have been studied. This is the report of a study which attempted to find for what (low) frequencies (long wave-lengths) of excitation it is permissible to ignore the wave-passage effects, for what (high) frequencies (short wave lengths) the wave-passage effects must be included in the analysis, and what simplifications may be possible for excitation by intermediate frequencies. The study considered simple buildings supported essentially by surface foundation only.
