ABSTRACT
The cooperative research achievements for analysis and evaluation of sand soil liquefaction in soil dynamics between USA and PRC in 1980’s are reviewed. The IEM’s recent progresses in soil dynamics and geotechnical earthquake engineering are introduced, including the soil nonlinear analysis under dynamic loads, determination of seismic settlements of weak foundations, evaluation of effect of saturated sand soil layers on the seismic surface ground motion and building responses, etc. Suggestions for the future cooperative research program in geotechnical earthquake engineering and soil dynamics between USA and PRC are finally presented. The suggestive topic “Study on performance-based seismic design of foundations and geo-technical structures” is divided into 4 aspects of research: 1. Dynamic properties of soils in large deformation range; 2. Classification of deformation and stability of foundations and geotechnical structures; 3. Analytical method for deformation and stability of foundations and geotechnical structures; 4. Effect of SSI on structure earthquake responses.
