Geng Yue is from Hebei Province of China. She got the B. Eng in Civil Engineering (Sep 2001-July 2005) from the Harbin Institute of Technology (HIT), Harbin, P.R. China. After that, she stayed in HIT, studying for her PHD degree.
In Feb 2008, She enrolled in University of Sydney as a Postgraduate Research student for the cotutelle PHD degree and will stay here for one year.
Research project - Static Long-Term Performance of the Concrete-Filled Steel Tubular Arch Bridge
Supervisor: Dr Gianluca Ranzi
For the large-span CFST arch bridge, the creep and shrinkage of the core concrete has a great effect on the static performance of the structure, increasing the deflection of the arch rib, and reducing its bearing capacity and stability. To insure the curve model of the arch rib, as well as the safety and the durability of the structure, research on the long-term characteristics of the CFST arch bridge is indispensable.
My research aims to have a better understand of the creep and shrinkage characteristics of the concrete-filled steel tube specimens and find out the effect of the long-term behavior of the core concrete on the static performance of concrete-filled steel tubular (CFST) arch bridges. Through all the analysis, a proper method will be developed to predict the long-term deformation and the stress redistribution of the CFST arch ribs, the effect of the creep and shrinkage of the core concrete on the deflection of the arch ribs, the bearing capacity and the stability of the structure will be specified and designing suggestion will be brought forward.
The project include experimental research on the long-term behavior of the CFST short column under sustained load, and the theoretical analysis of the long-term behavior of CFST specimens and CFST arch bridges with ABAQUS.
