A parametric study is applied to determine the dynamic cross interaction (DCI) of two closely spaced adjacent buildings focusing on the mean power of superstructures. Analyses are done for mat and pile foundations taking place on elastic half-space and layered elastic soil considering different embedment depths. Adjacent buildings are analyzed by the substructure method consisted of the thin layer method and finite element method in 3 dimensions. Consequently, 3 main factors are found to determine the DCI effect. First one is mass ratio of adjacent buildings that has detrimental consequences on the lighter adjacent building. Second one is rocking restriction that is beneficial effect especially on mat foundation and tall buildings. Third one is horizontal vibration power transfer between foundations having different embedment that induce due to the different horizontal movement of adjacent foundations at the same frequencies. This detrimental effect is observed on identical tall adjacent buildings placed on mat foundation. However, this effect cannot be observed on pile foundation. Moreover, more detailed parametric analyses are applied for mat foundation placed on half-space soil for height and mass of buildings and properties of soil.

The response of a continuous foundation structure supported on partially improved foundation soil was
recorded during an earthquake. The measured results show that partially improved foundation soil can
induce torsional response of the foundation due to the irregular soil-foundation system. A numerical
model considering soil-structure interaction was then established, and the numerical results were
compared with the observation data. Using the validated numerical model a parametric study was
carried out to investigate the torsional response of a continuous foundation structure with irregular soil
foundation system. It can be concluded from the study that eccentricities in the soil foundation system
would result in a torsional response. Particularly with different lengths of soil-cement piles in the partially
improved foundation soil, the generated torsional response can not be ignored during the seismic
excitation.

EFFECT OF ROCKING FOUNDATION INPUT MOTION ON THE INELASTIC BEHAVIOR OF STRUCTURES Reviewed

Oguz Can OGUT, Masafumi MORI and Nobuo FUKUWA

J. Struct. Constr. Eng. , AIJ Vol. 81 ( 721 ) page： 447-457 2016.3

Language：English Publishing type：Research paper (scientific journal)

A parametric study is applied to determine the effects of rocking foundation input motion (RFIM) on the nonlinear behavior of SDOF elasto-plastic structure considering soil-structure interaction (SSI). A new lumped parameter model considering SSI is constructed based on the results of the thin layer method (TLM) for different embedment ratios of foundations taking place on homogeneous elastic half-space. After that the soil-structure model is analyzed under some earthquake records. Consequently, it is claimed that by increasing ductility factor values, the effect of RFIM becomes more important especially for high-rise buildings having deep embedment ratios. The reason of this phenomena is considered that equivalent elastic stiffness of superstructure becomes softer for increasing values of ductility capacity, therefore the additional force coming from the rocking input motion becomes more important than inertial interaction for the response of the superstructure.
