Seismic site response and SSI in soft soils
Ground shaking from earthquakes can collapse buildings and bridges; disrupt utility services; and sometimes trigger landslides, floods, fires, and huge, destructive ocean waves (tsunamis). Estimates of losses from a future earthquake in the United States approach $200 billion. Eastern and Western Canada are exposed to earthquake hazards that may cause major disasters resulting in loss of life and substantial damage to property.
Site conditions may significantly affect the seismic performance of structures through amplification of earthquake motion. Recent destructive earthquakes have shown the effect of local site conditions as well as seismic soil-structure interaction on seismic performance of structures and the level of damges experienced by them. This project is focused on developing innovative soil and foundation improvement solutions to reduce the earthquake foundation input motion and increase the resistance of foundations against earthquakes.
