Description
The present study focuses on the resonant characteristic of a soil-deeply embedded circular foundation-superstructure system under compounded nonlinear conditions when subjected to lateral harmonic excitations. In this study, vibration tests are carried out. In the tests, the strain-dependent characteristic of soil layer, the boundary nonlinearity at the interfaces between the soil and foundation and the yielding of soil near the foundation are observed. It is concluded from the test results that, the shift of the predominant frequency toward the lower frequency region is mainly affected by the decrease in the stiffness of soil-foundation system due to the nonlinearity, rather than the effect of interaction between the soil-foundation system and the superstructure under small deflection condition.
