398 R. Inoue and T. Matsurnoto(a) ti-5 Component(b) E-W ComponentFigure 8. Sv for the record at Niigata from the 1983 Nihonkai-Chubu event.From Table 4, Figure 10 and Figure 11, the following can be seen: (1) Themaximum value of (SV)~ with h = 0.1% among the 29 components is 188 kine,and there are 7 components whose (SV)~ with h = 0.1% are larger than 110 kine.(2) The maximum value of (SV)~ with h = 2% among the 29 components is 70 kine,and there are 16 components whose (SV)~ with h = 2% are larger than 40 kine.6. ConclusionsThe results in the preceding section strongly suggest the need to examine thoseJapanese seismic design specifications.
