The Effects of High Ductile Structures with Embedded Foundation Including Soil-Structure Interaction

Abstract eng:
Seismic behaviors are evaluated when high ductile structures are supported by embedded foundation and interactive with their surrounding soil ground. Transfer functions are defined on the face of embedded foundation with sway and rocking motions. Physical parameters are selected out of various properties of interaction systems to investigate response behaviors such as ductility factors and natural periods of upper structure, as well as embedment depth and shear wave velocities of soil ground. Response measurement indexes are adopted among yield shear force, seismic input energy, radiation damping energy and cumulative plastic deformation for upper structures and base foundation excited with significant seismic motions. Effect of dynamic soil-structure interaction is consequently confirmed for high ductile structures supported with embedded foundation.
