Response Spectra for Liquefiable Sites: A Simplified Equivalent Linear Analysis Methodology
A simplified methodology is proposed for the computation of elastic response spectra at liquefiable sites, based on the widely used equivalent linear site response analysis method. The target response spectrum is obtained by frequency dependent interpolation between the elastic response spectra for “non-liquefied” and “liquefied” ground, the former computed for the native soil properties, without excess pore pressure buildup, and the latter for the liquefied soil properties. Apart from the structural frequency, the interpolation coefficient is also related to the factor of safety against liquefaction. In this way, the proposed methodology indirectly takes into account the initial segment of the seismic excitation, until the onset of liquefaction, which is of cornerstone importance for the evaluation of the overall ground response at sites with low and moderate liquefaction potential. Comparisons with results of nonlinear numerical analyses and field case studies verify the potential of the proposed methodology for preliminary design purposes.
