Nonlinear soil-structure interaction analysis of multistorey building

The interaction among structures, their foundations and the soil medium below the foundations alter the actual behaviour of the structure considerably than what is obtained from the consideration of the structure alone.

description The interaction among structures, their foundations and the soil medium below the foundations alter the actual behaviour of the structure considerably than what is obtained from the consideration of the structure alone.

Such an analysis neglects the flexibility of foundation and compressibility of soil mass. It is also assumed, conventionally, that the soil is behaving linearly neglecting that fact that it is nonlinear in nature. In this study an attempt has been made to carry out a two dimensional linear and nonlinear analysis of the problem of a multistory building incorporating soil-structure interaction with respect to nonhomogenous soil properties in Malaysia.
