摘要

The interaction of soil, foundations and structure (SFSI) depends on numerous parameters, although the effect of vibrations due to earthquake is dominant: foundation manner, and properties of soil, foundation and structure. Important are the characteristics of vibration caused by earthquake (frequency contents, pick acceleration, etc.) depending on soil quality. The paper describes the kinematics and inertia interactions and their influence on the behaviour of the structure. A different design model for SFSI is described and analysed. Consequently, the decomposition of the soil-pile-structure response is presented and steps in modelling and analysis are given. The emphasis is on the simplified model and foundation on piles.
