Description
Earthquake damage to bridges depends not just on shaking but on how regular the bridge's shape is. Seyed Hadi Rashedi and Alireza Rahai assessed that risk in a 2026 study of continuous reinforced concrete rigid-frame bridges in Iran. They began with one real bridge in a regular layout as the reference case.
From that base they built a family of models, varying the ratio of span lengths, the ratio of pier heights, and the skew angle of the piers. Each model faced a set of near and far earthquake records in a detailed 3D simulation. Fragility curves then gave the odds of four damage levels, from minor to collapse. Uneven pier heights hurt most: highly irregular bridges faced far higher odds of severe damage and collapsed at much lower shaking intensity.
