Overview

Database analysis reveals structural typologies and connection details in industrial precast concrete buildings, highlighting key parameters for regional seismic fragility modeling.

Key Points

Classify non-residential precast concrete structures to establish an empirical structural taxonomy for regional seismic assessment and retrofitting initiatives.
Extracted structural and architectural records for nearly 700 precast concrete buildings from three comprehensive databases across Italy.
Categorized facilities constructed from the 1960s to the present by construction era, seismic design code status, structural framing type, and specific beam, column, connection, and roof element typologies.
Derived empirical frequency distributions and fitted statistical probability models to characterize key structural and non-structural parameters.
Identified prevalent structural configurations dominated by slender cantilever columns and hinged beam-to-column connections relying on friction or mechanical fasteners prone to unseating during earthquakes.
Established parametric probability distributions capable of stochastically generating representative building inventories for qualitative seismic response assessments and analytical fragility curve development.
