The figg team has studied designed or helped build 33 cable stayed bridges with main span lengths up to 1 750 and is engineer of record on 9 cable stayed bridges in the united states.
Cable stayed cradle system.
The cradle system is disposed along the length of the cable stay and located in a pre formed opening in a pylon.
Figg s award winning cable stay cradle system provides better serviceability ease of construction and a longer bridge service life.

The cable stayed bridge design system with all its variation is a cost effective and more aesthetically appealing means of spanning medium to long distances.
The design of the cable stayed bridge supports itself.
A cable stay cradle system cradle system for cable stayed bridges is mounted onto a cable stay the opposite ends of which are attached to anchors on a bridge deck.
It can be an unstable design in certain environments.
A cradle system carries the strands within the stays from the bridge deck to bridge deck as a continuous element eliminating anchorages in the pylons.
A cable stayed bridge should not be installed in a region that is known to experience high wind speeds on a consistent.
Cable stayed cradle system bridge is one of the newest variants.
Testing is complete on a new cradle system for cable stayed bridges designed by figg engineering group figg that will make cable stayed bridges more affordable to build and allowing engineers to design a greater variety of pylon shapes.
Cable stayed cradle system bridge a cradle system carries the strands within the stays from bridge deck to bridge deck as a continuous element eliminating anchorages in the pylons.
It will allow this type of bridge to be even more economical thus attractive for many major spans around the world.
In this new system a continuous cable stay runs from the bridge deck through the cradle in the pylon and back down to the.
Each epoxy coated steel strand is carried inside the cradle in a one inch 2 54 cm steel tube.
The innovative cable stay cradle system designed by figg engineering group initially for the maumee river crossing and for use on future cable stay bridges will revolutionize cable stay bridge design.
Each epoxy coated steel strand is carried inside the cradle in a one inch 2 54 cm steel tube.
List of the cons of a cable stayed bridge.
You can also use cradle systems multiple span options like the jiashao bridge or extra dosed options to create the needed supports for a consistent deck that can support the expected weight that will be placed on the structure one day.
The cradle system includes axially spaced sleeve centering plates that have radially spaced holes through.
These cables are continuous which means that this bridge has no anchorages in the pylons and its cables can be removed inspected and replaced individually.
