| Popis: | Nonstructural components (eg, suspended ceilings, equipment, and piping systems) resonate with buildings and could suffer severe damage during strong earthquakes. The aim of the present study is to evaluate resonance properties based on the duration of ground motions for elastic nonstructural components. First, it is theoretically shown that the value of the dynamic amplification ratio (DAR) of nonstructural components can be bounded to a certain domain according to the extent of structural damping. Second, we propose a direct method for evaluating the expected value of the DAR, which does not require a time‐history analysis, using distinct dimensionless values related to structural properties and earthquake ground motions. Finally, the proposed estimation method is statistically verified based on time‐history analysis using thousands of recorded ground motions. |
