Abstract
An actual sesmic design may have to consider the partial embedment effect on soil-structure interaction concerning the site condition and structure planning. A finite element method is effective to calculate such a complicated foundation model. However, strong computer power is necessary to calculate the rigorous solution as for the effect of partial embedment. This paper describes a simple method to estimate complex soil impedance function and foundation input motion for partially embedded foundation. A present method provides considerable results comparing the 3-D boundary element method on the dynamic characteristics of various types of embedded foundations, and it is concluded that this method can be applicable for practical design use.
