SITE DEPENDENT EARTHQUAKE MOTIONS

A statistical method for modeling time varying earthquake induced acceleration levels which will produce smooth response spectrums of the desired shape and amplitude levels is developed. Specific records are derived to simulate a mean spectrum developed from historically recorded rock motions and also for AEC Regulatory Guide spectrum. The synthetic rock motion is then used as the input motion to a number of site conditions simulating stiff, deep cohesionless and soft to medium clay and sand sites using the computer program SHAKE. The results are compared to mean spectra for similar sites derived from historically recorded motions and shown to provide reasonable engineering estimates of site motions. /ASCE/
