5Modal testing — is a form of vibration testing of an object whereby the natural (modal) frequencies, modal masses, modal damping ratios and mode shapes of the object under test are determined. A modal test consists of an acquisition phase and an analysis phase.… …
6Peak ground acceleration — (PGA) is a measure of earthquake acceleration on the ground and an important input parameter for earthquake engineering, also known as the design basis earthquake ground motion (DBEGM)[1] Unlike the Richter and moment magnitude scales, it is not… …
7Antwortspektrum — Ein Antwortspektrum ist ein Diagramm, das die Reaktion (=Antwort) eines (idealisierten) gedämpften Einmassenschwingers oder einer Menge von Einmassenschwingern auf eine definierte Schwingungsanregung ihrer Fußpunkte als Funktion der Frequenz… …
