Accuracy Assessment of Nonlinear Seismic Displacement Demand Predicted by Simplified Methods for the Plateau Range of Design Response Spectra
Figure 10
Assessment of the nonlinear displacement demands for soil class D and four values of strength reduction factors, to . The ratio of predicted to actual (NLTHA) displacement demand is plotted with respect to the period. The plateau period range of the corresponding response spectrum (0.20 s to 0.80 s) is considered for the assessment.
