Horizontal Curvature
Estimated Time: 2–3 min | Difficulty: Intermediate
Question
In horizontally curved steel girder bridges, which structural effect becomes significant compared to straight bridges?
Explanation:
Curved alignment introduces torsion and warping effects due to eccentric load paths and radial geometry. This increases demand on cross-frames and lateral bracing systems.
