Abstract:
In order to analyse the elasto-plastic response of structure under the seismic action, this paper studies an elasto-plastic response spectrum. The basic equation of an elasto-plastic response spectrum is established and the constant-ductility strength demand spectra are calculated. The methods of elasto-plastic spectra established by relationship among the strength reducing coefficients and the ductility coefficients as well as the structural periods are described. Four kinds of elasto-plastic response spectra are deduced from referring to the elastic response spectrum. The calculation result shows that the elasto-plastic response spectra proposed here are similar to Fan Lichu’s elasto-plastic response spectra under the condition of hard soil and small ductility coefficient,and the elasto-plastic response spectra proposed here are relatively safe under the condition of soft soil and large ductility coefficient.
