Mapped Spectral Response Acceleration Ss And S1 Values
shahidthanvi posted a topic in Seismic Design
Ss and S1 values obtained from GSHAP are Ss=1.13 & S1= 0.45 where as that from USGS OFR are Ss=0.78 & S1=0.224 for town (Thana District Malakand) out of USA. Can I input these values in ETABS directly; if yes then which one OR do I need some further calculation based on these values? thanks for... -
