AbstractA relatively simple and direct method is presented for determining quantitatively the foundation flexibilities under structures. Data required are the modal properties and masses. The procedure is illustrated by finding the rotational and horizontal foundation stiffnesses for a 15- storey concrete building on clay, a 9-storey concrete building on dense sand, and a bridge pier founded on clay. On the basis of the fixed-base frequencies obtained, an assessment is made of the importance of the foundation flexibilities on the modal characteristics of these structures.
