In this paper, k-means algorithm has been used to disaggregate seismic parameters to evaluate their inter-correlations. A goal is to quantify in a disaggregated way the weights and effects of each parameter with respect to other ones. From the database, about 4900.0 data, divided into 22.0 categories, have been collected. The main divisions regard...

Context 1
... the studied ZS16, in the seismic characteristics, it is indicated that "very wide representation of M w > 5.0" was registered (IGME 2015); therefore, the "type 1" spectrum was here adopted. Figure 8 shows Sa trends in the function of the structural period, T, for a classical return period of 475 years (curves of this study are represented by mean values). ...
Context 2
... Fig. 8, it is possible to see that the vertical Sa by Eurocode (2004) (lower red line) provides good results for the site, whereas the horizontal Sa (upper red line) overestimates the response for soil A. This could indicate that the clustered mean curves approximate the vertical Sa curves ...
