Abstract
The study of which the report presents the first results, was undertaken with a view of eventually filling this gap and furnishing procedures for the dynamic analysis of plastic structure under any loading history. Therefore, rather than solving particular problems, the attention is focused on recognizing general characteristics, outlining avenues of approach, and so on. A substantial portion of the report deals in particular with periodic loading of structures which behave symmetrically with respect to the sign of the loads; it is possible to derive some rather general results on the rigid-plastic response in this case, without any qualifications of the structural type. However, the symmetry assumptions are particularly realistic in the case of rectangular frames subjected to horizontal loads, and specific results pertaining to these structures are also presented, including multi-degree of freedom response.
