Summary
In this paper structures acted on by dynamic ground shaking and exhibiting a rocking motion are considered. The finite element analysis developed for an industrial chimney shows how this assumption is appropriate, when dealing with this type of structure, where the crack distribution helps to identify pivotal points, around which rotations occur. Modeling is then performed by moving to a distributional environment, where the problem may be set up in one unique formulation. This treatment is able to embed the impacts that occur during the motion at the pivotal points when sign changes occur in the rotation variable, and, moreover, to simplify and lighten the subsequent computational implementation.
