The Eleanor Schonell Bridge across the Brisbane River connects Dutton Park to the University of Queensland campus
Challenge
In its capacity of Bridge Design Consultant, SYSTRA (then IBT):
- Developed the concept design,
- Lead the detail design stage and undertook the global modelling, deck / stay design, including construction engineering
- Provided the inputs for GHD to design the pylons and foundations.
Approach
The 20 m wide bridge carries two lanes of traffic and two sidewalks with canopies for pedestrians and bicycles. It is designed to accommodate a future light rail track.
The main cable-stayed bridge consists of a 183 m main span and 30 m and 73 m side spans. Two planes of stay cables in a “harp” arrangement support the steel-concrete composite superstructure. The concrete pylons rest on concrete pile caps at water level. The pile caps are supported by 1.5 m diameter bored piles.
Benefit
This project received the 2008 Golden State Award, ACEC’s (CELSOC’s) highest honor for projects engineered in the State of California, and the ACEC 2008 Excellence in Engineering Design Honor Award.
