Soil-Structure Interaction of High-rise Building Resting on Soft Soil

ABSTRACT
Taking one real high-rise frame shear-wall structure in Fujian province of China as an example, the influences of soil-structure interaction on the super-structure are studied with ABAQUS procedure. The peak response of absolute acceleration, story drift, moments at beam ends, as well as inner force of columns and shear walls are analyzed under two orthogonal horizontal directions seismic excitations. Then the influences of field nonlinearity on seismic response of high-rise building are summarized and the rationality of reduction factor for soil-structure interaction calculation specified in Chinese seismic code is discussed.
It is concluded that it’s usually safe for most stories of the high-rise frame shear-wall structure when the soil-structure interaction considered according to Chinese seismic code; however, the seismic response
