RICERCA DI SISTEMI DI PROTEZIONE APPROPRIATI PER SCHEMI PREFABBRICATI RICORRENTI

The paper presents the layout and the first development of a research targeted on the study of seismic protection devices at low cost to be inserted in the joints of precast concrete building systems. The first part of the work is targeted to the classification of devices, with particular attention to construction details, the compatibility of seismic code and the costs of production. The second part of the work is targeted to the identification of technological strategies that can improve the expected seismic performance to prefabricated systems . With reference to a case study, was established the increase of the seismic capacity of structural precast systems and the reduction of cost construction of the elements in order to offset the cost of the devices.
