Earthquake Resistant Design Parameters needed are:
Peak Ground Acceleration
Response Spectral Acceleration at 0.3 sec
-- short-period ground motion, most significant for buildings near 3 stories
Response Spectral Acceleration at 1.0 sec
-- mid-period ground motion, most significant for buildings over 10 stories
|
Earthquake Intensity Parameters are needed in terms of:
Modified Mercalli, Rossi-Forel, or San Francisco scales
