Overview

Probabilistic structural analysis demonstrates substantial reductions in collapse and damage risks across retrofitted precast concrete buildings, highlighting the efficacy of standard code upgrades.

Key Points

To evaluate the probabilistic seismic vulnerability and performance of standard code-compliant retrofit strategies across single-story precast reinforced concrete buildings constructed between the 1960s and 1990s.
Modeled four archetypes of single-story precast reinforced concrete industrial buildings representative of designs from the 1960s to 1990s situated in a high seismic hazard area.
Conducted a probabilistic assessment coupling non-linear pushover analyses, multi-stripe dynamic analyses, and fragility derivation methods to evaluate usability preventing damage (UPD) and global collapse (GC) performance limits.
Invasive global retrofit measures attained safety targets fully compliant with current structural codes for the global collapse limit state.
All examined retrofit interventions substantially decreased the mean annual failure rate for usability preventing damage, maintaining all building archetypes within acceptable safety margins.
Local roof-level retrofits and connection detailing enhancements showed comparable effectiveness to invasive global interventions in controlling seismic fragility.
