Project Background:
The deterioration of steel-concrete composite structures due to corrosion of structural steel and concrete degradation affects the durability and safety of the structures. UHPC and FRP are two promising alternation to concrete and steel, respectively. FRP-UHPC hybrid beams are a novel type of composite beams, and have the advantage of light weight, high strength, excellent durability, environmental friendly and rapid construction, but research on them is still scarce, which restricted the widespread application.
Aims & Goals:
1. To investigate shear behavior of GFRP bolts to provide calculation method for shear bearing capacity and shear-slip model;
2. To propose the creep and shrinkage model of UHPC under room temperature curing;
3. To propose the ultimate and serviceability limit state design method for FRP-UHPC hybrid beams.
