Damping Estimation from Seismic Records
A review of the commonly used viscous model for damping is presented as well as of expressions recently developed for the expected value of the first mode damping ratio of soil-structure systems. The statistical expressions show that the parameter that is best correlated with damping in steel and concrete buildings is building height while in wood and masonry structures it is the spectral acceleration at the fundamental period. The paper illustrates that the high variance with which damping ratios are typically identified (compared to frequencies) is the result of low Fisher information in the (relatively short) seismic response transients.
