Creep and Shrinkage of the Gateway Bridge Concrete
The recently-completed Gateway Bridge is the largest concrete portal bridge in the world. Spanning Quarries Reach of the Brisbane River, Brisbane, Queensland, Australia, the 260-meter main span consists of a single cell box girder varying in depth from 15 meters at the piers to 5 meters at the center span. The Swiss designers of the main span used the CEB-FIP Model Code, while the designers of the approaches and foundations used the NAASRA Bridge Design Specification. A testing program was initiated to ascertain if the creep and shrinkage characteristics of the mainspan concrete conform to the approach of these two codes. Comparisons of the experimental results and the theoretical CEB-FIP/NAASRA predictions are presented. Various modifications to both codes are postulated, with reference both to work presently being conducted and future recommended work.
