- Abstract:
- Synthetic ground motion parameters are usually adopted for the characterization of seismic signals, because of their effectiveness in synthesize the main information about amplitude, frequency and duration of earthquakes. The influence of focal mechanism on ground motion parameters and the differences or similarities for areas characterized by different prevalent faults will be discussed in this paper. The main aim of the study is to clarify the possibility of utilization of spectrum compatible accelerograms independently by their fault typology, to derive a set of design accelerograms for advanced structural and geotechnical analyses in given areas. Particularly, it will be demonstrate that care should be taken, because neglecting the source mechanism might lead to the loss of important information (i.e. duration and frequency content) about ground motion nature itself.
