Abstract: Commonly used simplified one-dimensional nonlinear seismic site response analyses employ constitutive models based on a variation of the hyperbolic model to represent the initial stress-strain backbone curve. Desirable ...

Abstract: Cyclic behavior of soils is often modeled using the Masing rules. When these rules are applied, hysteretic damping at large strains is overestimated. A non-Masing hysteresis model that reduces the size of hysteresis loops ...
