GNGTS 2023 - Atti del 41° Convegno Nazionale

Session 2.2 GNGTS 2023 characterized by buildings of 2, 3 and 4 floors, with an average height of the floors between 2.50 m and 3.49 m, which have residential, commercial or storage use and roof in timber and reinforced concrete. Results and discussion The results obtained by the proposed approach are presented in Fig. 3 in terms of fragility curves. The results refer to the populations of 3-storey buildings, be part of MUR1, prone to the partial overturning mechanism of the 2 nd and the 3 rd floor. In the plots, the fragility curves shown in grey correspond to the “moderate” damage, while the ones in black correspond to the “complete” damage. Moreover, while Fig. 3a) contains the fragility curves derived by considering an isolated façade wall, i.e. by excluding the presence of any kind of connection of the wall with the adjacent ones, Figures 3b), 3c), 3d) report the fragility curves obtained by taking into account the following effects: the interaction between the overturning façade and the transverse walls (Fig. 3b), the interaction between the overturning façade and coplanar walls of the adjacent SUs (Fig. 3c); the interaction of the overturning façade with both the transverse walls and to the coplanar walls of the adjacent SUs (Fig. 3d).
