|ANZAC Bridge | Australia | Sixense Context. The ANZAC Bridge is an eight-lane cable-stayed bridge in the west of Sydney. The bridge is 32.2m wide and the main span is 345m long. The reinforced concrete pylons are 69m high and support the deck by two planes of stay cables.The bridge can carry a maximum of 180,000 cars per day and is a critical infrastructure of the global Sydney road network.www.sixense-group.com|

RION-ANTIRION BRIDGE, GREECE
Period of the service: 2004 – 2020
Duration of service: 16 years
The Rion-Antirion bridge (Harilaos Trikoupis Bridge) links mainland Greece to Peloponnese at the west side of the Corinthe Gulf near Partas. It is 2.2 km long, supported by 4 diamond shaped pylons.
The environment in which the bridge was constructed combines a number of physical challenges and thus makes this project particularly complex: a strait of about 2,500m width, deep water (up to 65m) combined with deep soil strata of weak alluviums, possibility of strong seismic activity, tectonic movements and adverse high wind actions.
A Structural Health Monitoing (SHM) system was specially designed to survey the behaviour of the bridge subjected to this difficult environment.
Real-time and history
Installed in 2004, the monitoring sytem provides highly reliable and useful information about events occurring on the bridge and the response of the structure.
Real time alerts as well as a database of historical information allows the concessionnaire, Gefyra, to secure the daily service, optimise the periodic maintenance and ultimately asess and extend the design life of the structure.
In particular the SHM system provided:
- alerts concerning exesssive stay cable vibration in 2006, resulting in an upgrade of the structure with cable dampers which reduced the amplitude of vibration by four
- verification of the remaining fatigue design life of cable gussets using the historical database of cable loading
- optimisation of data by using a smart algorithm which record high sampling data file during specific seismic events.
Structural Health Monitoring (or SHM) uses permanently installed sensors to generate continuous data. A specific software enables to display the data in smart graphics and generates alerts. It is used in conjunction with spot check inspections to enable relevant structural data analysis.
Its aim is to maintain infrastructures, extend their working lives, and detect and forecast their faults.
We monitor the structure and its environment (usage, weather, etc.) simultaneously by integrating a varied range of measurements, with the majority of data being gathered automatically, including satellite measurements.
The data is processed to provide relevant indicators that operators can reliably use to optimise the operation and maintenance of their structures.
Our experience allows us to conduct SHM under challenging conditions (in confined spaces, working at height, etc.) by offering durable instrumentation for a broad range of applications, including extreme environments, offshore structures and potentially explosive ATEX zones.

|Anzac Bridge | NSW Environment, Energy and Science SHR Criteria a) [Historical significance] Anzac Bridge has historical significance as it is a contemporary solution to the problem of conveying road traffic over Johnstons Bay, which was part of an important transport route from Sydney to the north shore and Parramatta since the mid nineteenth century, known as the five bridges route.www.environment.nsw.gov.au|

|The Anzac Bridge is a world standard bridge in scale, aesthetics and design features. The experience of crossing the bridge is cathedral-like, with its vaulted canopy of stay cables. The subtle sweep of the bridge’s cantilevered deck, which links into the arterial road network and is supported at either end by monumental reinforced concrete towers, forms a striking and integral part of the Sydney skyline. It has quickly become one of the iconic images of Sydney, particularly for those who have views of it, cross it to work by road or bike, or use its highly visible towers as an aid to urban navigation.|
|SHR Criteria f)|
|The Anzac Bridge is the largest cable stayed bridge in NSW, and indeed Australia (other examples of cable stayed bridges in NSW are mainly footbridges).|
|SHR Criteria g)|
|The Anzac Bridge is a representative example of a reinforced concrete cable stayed bridge in the state. It is currently the longest such bridge in Australia. Other, earlier examples of cable-stayed bridges are the Westgate Bridge in Victoria, and the Batman Bridge in Tasmania.|
