| Abstract: | There is an MS4.7 earthquake occurred in Jinta County on March 21, 2016 11:29. The main shock records of this earthquake obtained by 5 strong motion stations of Gansu Strong Motion Network. After routine processing, 15 zero-baseline corrected three points peak accelerations were obtained. The acceleration records (PGA value) of station 62XID, which is type of soil base, were selected and analyzed. And the corrected acceleration, velocity and displacement time history curves as well as acceleration response spectra were plotted. This study provides an important reference for seismic damage investigation in western China. |
