Overview

Simulation study reveals the structural impact of explicit panel modeling on single-storey precast buildings, highlighting the critical role of external cladding in seismic vulnerability.

Key Points

To assess how explicit modeling of external closure panels influences the seismic response and vulnerability of existing single-storey precast industrial buildings.
Simulated single-storey precast buildings representative of Italian construction practices from the 1970s and 1990s.
Explicitly modeled two cladding typologies—masonry infills (1970s archetype) and precast reinforced concrete panels (1990s archetype)—instead of treating them purely as participating mass.
Explicit cladding modeling demonstrated that external panels significantly alter the global structural response compared to standard mass-only approximations.
Identified that both masonry infills and precast concrete panels actively contribute to structural stiffness and dictate seismic vulnerability in precast building stock.
