Abstract

The influence of the foundation geometry on the antiplane impulse response of an embedded foundation is the topic. The foundations of a semicircular and a rectangular cross section are selected as characteristic examples. First, the impulse response for the semicylindrical foundation is obtained from its admittance derived by Luco and Trifunac. Then it is compared with the impulse response of the rectangular foundation as obtained by Thau and Umek. On the basis of this comparison it can be concluded, that the foundation geometry does not decisively influence its antiplane impulse response.
