Abstract
The purpose of this paper is to present results of calculations of seismic response of the old Parma Bell Tower with and without the rotational, rocking seismic effects as modeled in the European seismic code: Eurocode 8 (part 6: Towers, Masts and Chimneys). A detailed, finite element model of the tower was prepared, which led to the solution of its eigen problem and to conventional dynamic, response modal analysis. Next a simplified rod model, equivalent to the detailed finite element model was prepared, taking into account soil compliance as well as the rocking excitation effects. The results of computations show rather substantial, 30–40 % contribution of the rocking excitations in the overall seismic response.
