Damping Modification Factors for Pile–Induced Filtering Effect

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Period–dependent Damping Modification Factors are usually applied to the 5%–damped pseudo–acceleration response spectrum at free field conditions to derive the seismic demand for structures with damping ratio other than 5%. Likewise, the response spectrum at the foundation level of pile–supported structures may differ from the free field ...
