Abstract
In this research, horizontal dynamic response of foundation on homogeneous half-space was investigated using physical modeling. In order to carry out a comprehensive study on the effect of embedment depth ratio on horizontal impedance functions, 173 different tests in three series were conducted. In these tests, the embedment ratio of footing was increased from zero to 0.5 and finally reached to one by implementing the mentioned sand raining method. In each series of tests, the steady-state response of footing to horizontal vibrations was investigated. Using recorded data and related motion equations, foundation responses were analyzed. The obtained results were presented by graphs of horizontal impedance functions of square foundation on homogenous half-space against dimensionless frequency. Comparing horizontal impedance functions shows that an increase in embedment depth ratio resulting from amplifying impedance function coefficients up to dimensionless frequency of 3.5 Hz.
