Transcript C&Y, SS, Vs=600

Developer Scope
• Ground Motion Model (median, standard dev)
– Ground Motion Parameters:
• Horizontal components (Ave Horiz, FN, and FP)
• PGA, PGV, PGD
• Pseudo spectral acc at 5% damping: 0-10 sec
– Applicable Magnitude Range:
• 5.0 - 8.5 (SS)
• 5.0 - 8.0 (RV)
– Applicable Distance Range:
• 0 - 200 km
– Fault Types
• Strike-slip, Reverse, Normal
– Site Classification Scheme
• Developers select their preferred classification scheme
• Need not include soft-soil

Key Issues
• Oversaturation
– Is it due to the aspect ratio, or the magnitude?
• Use of Aspect ratio
– Are aspect ratios used in NGA consistent with
aspect ratios currently used in hazard analyses?
– Correlation with style-of-faulting
• Dependence on dip
– Is this dip effects or a regional effect?
Key Changes from
Previous Models
• Site classification
– Vs30
– Depth of soil term (Z1.0 or Z1.5)
• Source
– Oversaturation with magnitude
– Aspect ratio as a key parameter
• Non-linear site response
– Based on median rock PGA including event term
