Seismic scenario analysis of precast reinforced-concrete buildings at the large scale

Precast reinforced concrete structures have been widely adopted to build industrial facilities, although their high seismic vulnerability highlighted by the extensive damage occurred after the 2012 Emilia Earthquake. In this work, a scenario-based methodology for the fast seismic assessment of precast buildings is proposed to provide a uniform approach at the territorial scale. The fragility curves of common precast frames are developed in a parametric framework. Thus, two different methods for the seismic scenario analysis are illustrated. The availability of a method for the analysis of a diversified portfolio of precast buildings paves the way for the seismic risk assessment of large industrial clusters.
