Overview

Randomized trial investigates seismic performance of a curved bridge, indicating implications for design safety.

Key Points

  • This research aims to assess the seismic performance and damage evolution of a curved continuous rigid-frame composite girder bridge under various ground motions.
  • Constructed a 3D finite element model incorporating pile-soil interaction and nonlinear behaviors.
  • Conducted nonlinear time-history analyses using near-field and far-field pulse records.
  • Applied the fiber section capacity-to-demand ratio method to evaluate pier damage.
  • Near-field pulse-like motions lead to the most adverse structural responses, with long-pulse records causing significant displacements.
  • Under E2 seismic levels, high damping rubber bearings dissipate energy, protecting piers but increasing deformation on joints.
  • Tallest hollow thin-walled pier shows a capacity-to-demand ratio of 0.82, indicating moderate yielding with complex internal forces.
