ABSTRACT

Rocking motion of rigid blocks has been the subject of many research works. Indeed, many real structures under various kind of loads can be modeled in such way.

A first study on the subject was due to Housner (1963), which was inspired by the survival of some structure to the Chilean earthquake of May 1960. Several other works deals with the dynamics of one block (Facchini et al., 1994; Zhang & Makris, 2001; Makris & Konstantinidis, 2003; Lenci and Rega, 2006; Di Egidio and Contento, 2009).
