On the damping adjustment factors for earthquake response spectra
Damping adjustment factors for converting 5%-damped earthquake response spectra to other damping levels are evaluated in this paper. The evaluation is based on statistical analysis of spectra of 1047 horizontal components of earthquake ground shaking recorded between 1933 and 1994. The dependency of damping adjustment factors to response period is studied. Results of the evaluation are compared to the damping adjustment factors embodied in the current seismic design code provisions and guidelines which are based on the spectrum amplification factors of Newmark and Hall.
