Outline of Final Research Achievements

Geotechnical centrifuge tests were performed on soil-footing-superstructure models to investigate response of shallow foundation structures during strong shakings. Superstructure acceleration amplitudes tended to reach the limit, although ground surface acceleration amplitudes increased with increasing input motions. The ultimate response of the superstructure depends on the overturning moment limitation that was caused by local soil failure under the footing edge. Risk of overturn of a structure is small when the safety factor of the bearing capacity is large. Centrifuge tests are also performed to examine the dynamic response of structures supported by shallow foundations on soft clay reinforced by soil-cement grids. Soil-cement grids were effective at controlling foundation settlements in most cases. The more significant foundation settlements were caused by extensive crushing of the soil-cement when footing rotations were extremely large.
