- SCEC Workshop on 3D Site Effects in Physics-Based Ground Motion Simulations
- Organizers: Domniki Asimaki (Caltech), John Anderson (UNR), Ricardo Taborda (U Memphis), Jon Stewart (UCLA)
- Date: Tuesday, May 5, 2015 (09:00-14:30)
- Location: SCEC Media Room (ZHS 165), USC, Los Angeles, CA
- Participants: 25 (by invitation only)
Overview
A 1-day workshop on the integration of 3D nonlinear site effects in physics-based ground motion simulations will be held at the University of Southern California on May 5. The workshop will be funded by the Southern California Earthquake Center (SCEC), and is intended to identify and prioritize research needs in the realm of ground response and ground deformation simulation for large-scale seismological models. Specific areas that the workshop will be focusing on include:
- Material (constitutive) models for soils in seismological models: Moving from 1D to 3D in regional-scale simulations
- Parameterization of material models on regional scales: How to deal with scarce and sparse input parameters?
- Large scale simulation and computational challenges (including multi-scale approaches to nonlinear site effects)
- Coupling with engineering applications (e.g., SSI, distributed infrastructure systems, soil-city interaction simulations) and other effects (topography/geometry).
