Overview

This approach minimizes damage to concrete piers in seismic events, suggesting better design parameters for resilience.

Key Points

  • The research aims to develop and validate a performance-based seismic design framework for segmental concrete piers.
  • Developed a two-tier design methodology incorporating capacity-demand-diagram and fragility analysis.
  • Assessed displacement demands of SPPC piers against seismic displacement targets.
  • Validated the framework through a comparison case study of SPPC piers and conventional piers.
  • Demonstrated SPPC piers' potential to minimize damage while maintaining overall bridge integrity.
  • Confirmed the framework's applicability and integration into existing seismic design practices.
