Seed idriss liquefaction potential analysis
WebApr 1, 2015 · The effect of structures on the liquefaction potential of foundation soils depends on both the characteristics of structures and soils, so direct applicability of the simplified methods (e.g. Seed–Idriss procedure or Chinese simplified procedure) to foundation soils beneath structures is impossible, unless the soil–structure–earthquake ... WebA method for the evaluation of the liquefaction potential index has been applied and the results presented in the paper show that the liquefaction risk particularly in the Saint Giuseppe La Rena site is high. A parametric analysis to verify the effect of the seismic design data on the liquefaction potential index was carried out, showing
