These record have been optimized to fit average acceleration spectra, average displacement spectra and average CAV of first components of FEMAP695 far-field record set.
"ETA20lc" series follow an exponentially intensifying profile that is consistent in CAV when compared to conventional GM scaling to match desired intensity. Optimization is for 120 Ts in 0.02-5 sec plus 10 points from T=5 to T=50 secs
acceleration points are in terms of g.
