A One-Dimensional Model Used for the Analysis of Seismic Site Response and Soil Instabilities: A Review of SCOSSA 1.0 Computer Code
Year: 2025
Type: article
Abstract: This review aims to provide a complete and comprehensive state-of-the-art of the computer code SCOSSA, which is a one-dimensional nonlinear computer code for the analysis of seismic site response and soil instability. Indeed, among the effects of earthquakes, the activation of landslide and liquefaction constitute two of the predominant causes of vulnerability of the physical and built environment. The computer code SCOSSA (Seismic COde for Stick–Slip Analysis) initially developed to evaluate the permanent displacements of simplified slopes using a coupled model, introduced several improvements respect to the past, namely: the formulation for solving the dynamic equilibrium equations incorporates the capability for automated detection of the critical sliding surface; an up-to-date constitutive model to represent hysteretic material behavior and a stable iterative algorithm for the solution of the system in terms of kinematic variables. For addressing liquefaction-induced failure, a simplified pore water pressure generation model was subsequently developed and integrated into the code, coupled with the one-dimensional consolidation theory. This review retraces the main features, developments and applications of the computer code from the origin to the present version.
