Representation of Earthquake Ground Motions

Chapter

Abstract

It is noted that the most important parameters of an earthquake ground motions are its maximum motion, predominant period and effective durations [1]. However, different from other loadings, earthquake induced loading and ground motion cherish high uncertainties in these aspects, as well as, more broadly, on its occurrence, magnitude, frequency content and duration. The uncertainties come from many sources: the energy suddenly released during an earthquake is built up rather slowly through tectonic movements; historical records over a time span of a couple of hundred years do not provide a complete picture of the seismic hazard. Moreover, the rupture and faulting process during an earthquake is extremely complex and affected by many parameters that are difficult to predict [2].
