To　study　the　influence　of　steel　wire　mesh　on　the　bending　properties　of　ultra-high　performance　concrete　(UHPC)　slabs,　a　bending　test　of　simply　supported　two-way　slabs　with　four　sides　was　carried　out.　The　chopped　fibers　in　UHPC　ware:　Steel　fiber　and　steel　fiber　were　mixed　with　polyvinyl　alcohol　fiber,　glass　fiber　and　basalt　fiber,　respectively.　The　research　parameters　were:　Number　of　layers　of　wire　mesh　and　glass　fiber　mesh,　pore　size　and　proportion　of　blended　fibers.　The　results　show　that　when　UHPC　is　single-doped　with　1.5vol%　steel　fiber,　the　ultimate　bearing　capacity　and　energy　absorption　at　25　mm　deflection　of　UHPC　slabs　with　3　layers　and　4　layers　are　increased　by　14.9%,　32.3%　and　14.1%,　25.2%,　respectively　compared　with　UHPC　slabs　with　2　layers　of　steel　wire　mesh.　When　the　total　volume　fraction　of　hybrid　fibers　is　1.5vol%　and　the　steel　wire　mesh　is　2　layers,　the　blending　of　1.0vol%　steel　fiber　and　0.5vol%　polyvinyl　alcohol　fiber　has　better　reinforcing　and　toughening　effect　on　UHPC　slabs,　and　the　UHPC　slab　mixed　with　0.5vol%　steel　fiber　and　1.0vol%　glass　fiber　or　basalt　fiber　has　a　stronger　ability　to　maintain　load　after　peak　load　than　1.0vol%　polyvinyl　alcohol　fiber,　namely　the　mixing　of　steel　fiber　with　higher　modulus　of　elasticity　non-metallic　fiber　is　advantageous　to　increase　the　post-cracking　bearing　capacity.　Compared　with　glass　fiber　mesh,　UHPC　slabs　with　steel　mesh　have　better　ductility　after　peak　load.　A　method　for　evaluating　the　flexibility　of　UHPC　slabs　with　peak　load　deflection　as　initial　cracking　parameter　was　proposed,　which　can　characterize　the　contribution　of　mesh　and　fibers　to　the　post-crack　toughness　of　UHPC　slabs.　Based　on　the　concept　of　effective　utilization　of　mesh,　the　theoretical　value　is　in　good　agreement　with　the　experimental　value　by　calculating　the　bending　capacity.　©　2022,　Editorial　Office　of　Acta　Materiae　Compositae　Sinica.　All　right　reserved.
