Seismic vulnerability assessment of clustered buildings in the historical center of timisoara: fragility curves for in-plane local mechanisms of collapse

The historical center of Timisoara, in Romania, is composed by clustered masonry buildings. The characteristics of these structural units were identified in a stock of 245 buildings, subdividing them into a set of typologies. A kinematic-parametrical analysis was performed for the typologies, in order to calculate the seismic vulnerability of them. Finally fragility curves, representing the exceedance probability referred to a determinate level of damage, expressed in terms of PGA, were derived
