Various ground shaking and damage parameters are examined for post-earthquake
applications. Peak ground motion values, elastic response spectra, spectrum intensity,
drift spectrum, inelastic spectra, hysteretic energy spectrum, and two improved damage
spectra are examined. The proposed damage spectra will be zero if the response remains
elastic, and will be unity when the displacement capacity under monotonic deformation
is reached. The damage spectra can be reduced to the special cases of normalized hysteretic
energy and displacement ductility spectra. The proposed damage spectra are promising for
seismic vulnerability studies and post-earthquake applications of existing facilities,
and performance-based design of new structures.
