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

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.

Automated summary

This paper investigates a variety of single-story precast frames through dynamic analysis, providing fragility curves for different vibration periods and studying the interaction with nonstructural elements. Analytical expressions for severe damage and collapse states are provided, enabling a new methodology for rapid assessment of fragility curves in precast buildings with different fundamental vibrating periods.
