Overview

Seismic performance analysis reveals vulnerabilities in precast concrete decks, implying a need for improved design practices.

Key Points

  • This study examines the vulnerability of precast concrete decks to vertical earthquakes and assesses current design methodologies.
  • Performed linear and non-linear analyses on a 25 m wing-shaped roof element.
  • Conducted Linear Static Analysis (LSA) and Non-linear Time-History Analysis (NLTHA).
  • Analyzed various coupled and uncoupled configurations to evaluate performance under vertical loading.
  • Identified critical vulnerabilities in long-span precast concrete structures during vertical seismic events.
  • Highlighted shortcomings in current design practices regarding vertical earthquake effects.
  • Provided insights for potential improvements in engineering design standards.
