What it is
A tied-arch bridge is an arch bridge in which the arch's horizontal thrust is resisted by a tie connecting its ends, rather than being transmitted to the ground or the abutments; the deck itself, or separate tie-rods, act as the tension chord. It is credited to Austrian engineer Joseph Langer.
What it led to
- Arch bridges on low-bearing-capacity ground, without large abutments
- Widespread use in railway and urban bridges
- Combination with modern steel and prestressed-concrete structures
