In this study a rotation depth of 0.7 Lem is assumed to derive a simple …
WebbThe hyperbolic soil model of Duncan and Chang is a nonlinear elastic model that has been shown to exhibit some drawbacks. These drawbacks include, for example, difficulty in detecting and characterizing unloading/reloading and,in specific cases, producing a nonphysical bulk-modulus value that can lead to an erroneous energy generation in the … Webb1 juni 2024 · Hyperbolic hardening with hysteretic damping model was adopted for the Seismic Soil-Structure Interaction (SSSI) analysis. • Adopted soil model possessed the shear strain hardening, dilation hardening, and pressure-dependent stiffness. •
