The diagrams are constructed based on the concept of separated variables of the energy spectrum. The concept is in engineering sense that a response energy spectrum of a nonlinear structure subjected to a given ground motion Seq {S (T ) ,h0 , μV , pV , μd , pd } can be expressed by the product between the corresponding elastic response spectrum S (T ) and the empirical formulas τ (h0 , μV , pV , μ d , p d ) . The formulas are derived by the statistic for the results of the time history simulations over a great number of earthquake ground motions, in which the adopted variables are viscous damping ratios, ductility factors, bilinear coefficients, relief velocity ratios and bilinear viscous coefficient ratios, etc. The accuracy of the parameters estimated by the performance-based diagrams is verified by a number of time history simulations.
