摘要：

The Large Synoptic Survey Telescope will be located on a seismically active Chilean mountain. Seismic ground accelerations produce the telescope's most demanding load cases. Consequently, accurate prediction of these accelerations is required. These seismic accelerations, in the form of Peak Spectral Acceleration (PSA), were compared for site specific surveys, the Chilean building codes and measured seismic accelerations. Methods were also investigated for adjusting for variations in damping level and return period. The return period is the average interval of time between occurrences of a specific intensity.
