ABSTRACT

The purposes of this research are to invest the correlations of ground motion parameters, including characteristic intensity (Ic), standardized version of cumulative absolute velocity (CAVstd), maximum incremental velocity (MIV), and the relationships with the damages of the buildings caused by the Mw6.4, 2016 Meinong Taiwan earthquake. To detect the validations of the hybrid simulation method, the waveforms of three stations near the epicenter are simulated and compared with the observations by employing the inverted source model of the Meinong earthquake. The comparisons between the observations and simulations demonstrate that the PGAs of the observations and simulations are well consistent and underestimations of the high-period contents are improved. Based on the excellent results of the method, the three parameters around Tainan city are calculated and displayed in this research. Apparently, most of the higher values of the three parameters distribute around the north-western regions of the epicenter of the Meinong earthquake, which coincides with the rupture direction of the earthquake toward the northwest. Almost all of the damaged buildings are located well within the values of MIV with 30cm/s, Ic with 316cm1.5/s2.5, and CAVstd with 418cm/s, indicating both of the results are agreeable to the previous studies and offering critical values of the three parameters to predict the potential earthquake-induced damages of buildings. Finally, we discover that two in pairs of the three parameters have high correlation coefficients and exceptional linear relationships between them. The correlation coefficient between MIV and Ic is 0.88, between MIV and CAVstd is 0.89, and between CAVstd and Ic is 0.99. The linear regression models of a couple of parameters are established to model linear predictor functions.
