The　expansion　joints　in　the　multi-span　simply　supported　bridge　can　be　eliminated　by　using　the　link　slab.　The　ultra-high　performance　concrete　(UHPC)　with　high　tensile　strength　and　crack　resistance　is　an　effective　material　for　the　link　slab.　However,　the　cast-in-situ　UHPC　link　slab　need　to　be　cured　with　steam　curing.　Therefore,　the　construction　processes　are　complicated　and　the　construction　quality　is　difficult　to　guarantee.　In　this　paper,　the　prefabricated　UHPC　link　slab　which　can　be　assembled　on　site　to　simply　the　construction　process,　accelerate　the　construction　speed　and　reduce　the　labor　cost　was　proposed.　Finite　element　models　of　the　prefabricated　and　cast-in-situ　UHPC　link　slabs　under　bending　were　built　by　using　ABAQUS.　The　ultimate　bearing　capacity　of　the　prefabricated　link　slab　was　nearly　the　same　of　the　cast　in　situ　and　the　crack　resistance　slightly　lower.　Finally,　the　influence　of　the　bolt　(used　to　connect　the　prefabricated　link　slab)　number　and　the　distance　from　the　bolt　to　the　edge　of　the　link　slab　on　the　crack　resistance　and　ultimate　bearing　capacity　of　the　prefabricated　link　slab　were　obtained.　©　2021　IABSE　Congress,　Ghent　2021:　Structural　Engineering　for　Future　Societal　Needs.　All　rights　reserved.
