The proposed work presents the seismic performances of a structural system obtained by connecting a moment-resisting frame structure with a vertical elastic truss, known in the literature as strongback. The strongback system is able to limit the development of excessive inter-storey drifts thus reducing potential dangerous phenomena such as weak/soft stories. In addition, the strongback system can be equipped with viscous dampers enhancing energy dissipation properties of the whole structure. In the present paper, an applicative example is developed in order to compare the effectiveness of both the strongback system and different dampers placements.

Abstract

The proposed work presents the seismic performances of a structural system obtained by connecting a moment-resisting frame structure with a vertical elastic truss, known in the literature as strongback. The strongback system is able to limit the development of excessive inter-storey drifts thus reducing potential dangerous phenomena such as weak/soft stories. In addition, the strongback system can be equipped with viscous dampers enhancing energy dissipation properties of the whole structure. In the present paper, an applicative example is developed in order to compare the effectiveness of both the strongback system and different dampers placements.
