| Abstract: |
The expansion joint of simply supported bridge makes the driving uneven and maintenance inconvenient. Therefore, it is the best way to reduce or cancel it. Link slab is a favourable substitute. At present, it is mainly used for small and medium span bridges. This paper attempts to introduce the link slab into long-span simply supported steel-concrete composite bridge. The numerical model of the whole bridge is built, and the influences of bridge span, debond length of link slab and thickness of link slab on the mechanical property of continuous bridge deck structure are studied. The results show that as the bridge span increases, the longitudinal tensile stress on the upper surface of the control section increases significantly. |
