It is essential to characterize the supplemental damping in buildings so that practicing engineers can understand the resultant effects of the additional damping. It is straightforward to characterize the overall system parameters representing the amount and the plan-wise distribution of the supplemental damping in a single-story asymmetrical building. Nevertheless, this becomes a difficult task in multi-story asymmetrical buildings. For this reason, this study first develops the effective one-story building(EOSB) that retains the characteristics of the two dominant vibration modes of the original non-proportionally damped multi-story asymmetrical building. By using the EOSB, the supplemental damping in the original multi-story asymmetrical building can be conveniently characterized. The relationships between the roof displacements of the original building and those of the EOSB are established. This enables the application of the response spectra constructed from EOSBs to estimate the peak roof displacements of the original multi-story asymmetrical buildings. |
