Troja Arch Bridge, Czech Republic

This bridge design multifunctional uses high arc resistance Macalloy 520 tension rod system in bridge hangers. Macalloy has developed a form of resistance to the single thread tired for the project.

 

The bridge Troja is the latest addition to the ring road in Prague and will carry a two-lane road, two tram lines and walking paths and cycling on the Vltava River .

 

Cross training single ply hangers made ​​the rigid bridge , and allows a greater length to height ratios to be achieved on the standard bowstring bridges.

 

The bridge has a span of 200 meters while the bow is only 20 meters high at its highest point relative to a standard bow string should be 50 meters high. This arch bridge design has helped save up to 40% in hardware.

 

Macalloy has supplied its high resistance system voltage 520 bar to use as bridge hangers . Macalloy has developed a form of resistance to the single thread tired for the project that has been tested in accordance with EN 1993-1-11 : 2006 and meets the requirements of Eurocode 3 for fatigue connections in bridges .

 

Architectural steel bars are tensioned using Macalloys device Techno – tensioning – a device for locally stressing tension rods using a turnbuckle connection.
