Overview

Analytical model evaluates seismic response in bridges, indicating improved resilience with rocking designs.

Key Points

  • The study aims to develop a 3D analytical model for rocking bridges and analyze their seismic response.
  • Developed a 3D analytical model considering local depth of compression and sliding bearings.
  • Conducted bidirectional shaking table tests on a reduced-scale rocking bridge.
  • Investigated the overturning stability under asymmetric Ricker wavelet ground motions.
  • Systematically examined response characteristics under a suite of recorded ground motions.
  • Increased overturning risk and amplified deck responses were observed under bidirectional loading.
  • The bearing boundary condition significantly impacted the ranking of intensity measures affecting bridge responses.
  • Integrating depth of compression adjusted the efficacy of intensity measures from duration-based to spectrum-based.
