Abstract: Ultra-high performance concrete (UHPC) is a material with high strength, high toughness and good durability. It can be used to replace normal concrete in steel-concrete composite beams to reduce the section size and dead weight of the beams. The interfacial properties between UHPC and steel are different from that between normal concrete and steel and they can be improved by some interface treatments. It is possible to reduce or replace the use of stud connectors by some interface treatments, with enough shear and uplift capacity of the interface. In this paper, two tests of non-steam-cured UHPC-steel composite beams with different interface treatments were conducted to investigate the interfacial properties between UHPC and steel. The interface treatment included headed studs connecting and epoxy based adhesive with sprinkled-in aggregates. The results showed that the composite beam treated by epoxy based adhesive with sprinkled-in aggregates behaved well compared with the composite beam using headed studs connecting.
