Abstract
Dynamic soil structure interaction (DSSI) is an important seismic design consideration for sustainable design of structures. Further, such interaction has been reported to be detrimental consequences superseding seismic codes in structure situated mainly in soft clay and liquefiable deposit as observed during past earthquakes, such as, 1964 Niigata earthquake, 1985 Mexico city earthquake, and 1995 Kobe earthquake. In practice, design is made based on assumption of fixed base condition with a perception of beneficial effect on the response of system based on few seismic codal guidelines and to avoid complexity in SSI modeling. In this context, present study is a humble effort to investigate the influence of DSSI in pile foundation-supported structure through scaled model study in very soft clay using shake table tests. This limited study indicates that lengthening of period is insignificant for stiff period of structure in soft clay which is in-general counter-intuitive. The reason may be foundation stiffness is considerably higher than superstructure. Further, it is observed from the acceleration signals that elastic forces may be significantly high in column as compared to pile head in particularly stiff period structures supported by pile foundation in soft clay, while an opposite trend is observed in moderately longer period of structure supported by similar foundation.
