Inelastic spectra for displacement-based seismic design

In recognition of the emergence of displacement-based seismic design as a p otentially more rational approach than force-based techniques, this paper a ddresses derivation of inelastic displacement spectra and associated topics . A well-constrained earthquake strong-motion dataset is used to derive ine lastic displacement spectra, displacement reduction factors and ductility-d amping relationships. These are in a format amenable for use in design and assessment of structures with a wide range of response characteristics. (C) 2001 Elsevier Science Ltd. All rights reserved.
