Inelastic Earthquake Spectra ----- Damage Spectra
Abstract eng: In this paper, firstly, a procedure of analysis of inelastic response spectra based on Park and Ang damage model, called RD spectra, is proposed. Secondly, considering ultimate limit state of structures and due to programming DBDS, a set of RD spectra are obtained. RD spectra consider both the effects of maximum inelastic displacement and the effects of cumulative hysteretic energy, fairly according with the actual inelastic behavior due to ground motions. Thirdly, corresponding to lots of time history analysis of SDOF oscillators and regress of the datum, an expression about RD spectra is presented, which can be used in seismic evaluation of structures in the future. Finally, the proposed RD spectra are compared with Rµ spectra in qualitative, and the comparison shows the importance of considering the duration of ground motions.
