Damping Modification Factor of Acceleration Response Spectrum considering Seismological Effects
Although seismological effects on the damping modification factor of an acceleration response spectrum (DMFa) are important, seismological parameters in existing formulations are generally not specified in seismic codes. This study aims to propose a practical DMFa formulation using parameters available from seismic codes to reflect the seismological effects. To this end, an analytical approach is developed to explore the seismological effects on DMFa. It is found that a bandwidth factor defined as the ratio of acceleration spectral values at 6 and 0s can appropriately reflect the seismological effects, and thus is incorporated into the proposed DMFa formulation for seismic design.
