ABSTRACT

Failures of many engineered structures implies the need for the 
improvement in the design and analysis method for critical structures, 
like bridges, buildings, dams, power generating facilities, etc.  
Case histories will be presented to show the need for research in 
soil-structure interaction.  Structures are founded on soils 
and/or rocks. The performance of structures is greatly influenced by the
behavior of soils. This phenomenon is termed soil-structure interaction (SSI).  
The severity of the interaction effect is greatly intensified when the 
system is subjected to strong motion shaking. An effective investigation of 
SSI requires nonlinear analysis involving both material and geometric 
nonlinearity.  The progress of this research will be summarized and problems 
required future research attention will be presented with an intent to explore 
the potential for interdisciplinary research among the faculty and student 
from different disciplines in the future.
