Overview

Randomized trial evaluates performance of controlled rocking bridges versus conventional systems, highlighting reduced damage and enhanced resilience.

Key Points

  • The aim is to develop a practical framework for analyzing and designing controlled rocking bridge columns to improve seismic resilience.
  • Developed a Modified Beam Theory-based Simplified Analytical Method for rocking columns.
  • Implemented a three-spring model for rocking connections using General Link elements in Midas Civil.
  • Calibrated and validated models against numerical datasets and experimental results.
  • Dissipative controlled rocking bridges show reduced base shear and foundation demands.
  • Achieved negligible residual drift and low damage while meeting code requirements.
  • Validated framework provides tools for practical design and supports broader adoption in bridge construction.
