Fast Seismic Assessment of Existing Precast Structures by Means of Fragility Curves: The PRESSAFE Methodology

ABSTRACT

In the present paper, a wide stock of internal and perimeter one-story precast frames has been investigated by incremental dynamic analysis, so providing the analytical fragility curve for each frame category for different fundamental vibrating periods. The interaction with nonstructural elements has been studied by considering three types of perimeter walls adopted in precast buildings. The analytical expressions provided for both severe damage and collapse states allow the definition of a new methodology that can be used for a fast assessment of the fragility curves of existing one-story precast buildings with a generic fundamental vibrating period.
