Dynamic Damage Assessment of Inter-Layer Seismic Isolation Buildings under Spectral Indicators

Abstract:

This study focuses on obtaining such damage probability curves based on representative Inter-layer seismic isolation buildings (ILSIB) in China metropolis using whole spectral indicator. 30 corrected random earthquake waves are selected to represent the variability in ground motion. Dynamic time history analysis is used to analyze the random sample of structures. Random damage scatter diagrams based on different spectral indexes are all achieved. Index of damage probability based Sd indicator is most precise in all the spectral indexes because of the least coefficient of variation. Fragility in Y axis is more serious than in X axis through careful analysis.
