Ultra-high　performance　concrete(UHPC)reinforced　with　meshes　has　the　advantages　of　light　weight，high　strength，and　good　durability.　UHPC　has　been　applied　in　the　fields　of　thin-walled　structures　and　engineering　reinforcement.　However，it　is　difficult　to　achieve　efficient　reinforcement　and　toughening　effects　with　a　single　mesh.　To　study　the　bending　properties　of　the　UHPC　two-way　slabs　reinforced　with　hybrid　meshes，three　hybrid　UHPC　slabs　of　steel　wire　mesh　and　glass　fiber　mesh，three　hybrid　UHPC　slabs　of　steel　wire　mesh　and　basalt　fiber　mesh，six　UHPC　slabs　of　single　mesh，and　a　non-mesh　UHPC　control　slab　were　subjected　to　the　bending　test.　The　effects　of　mesh　types，layers，and　laying　methods　on　the　failure　mode，bearing　capacity，and　bending　toughness　of　UHPC　slabs　were　discussed.　The　results　show　that　compared　with　the　single　steel　wire　mesh　and　single　glass　fiber　mesh　slabs，the　steel-glass　fiber　mesh　hybrid　slabs　exhibited　a　more　significant　hardening　phenomenon　after　cracking.　Under　the　synergistic　effect　of　continuous　meshes　and　hybrid　short　fibers，the　slabs　have　multiple　crack　propagation　modes　and　good　ductility.　In　the　case　of　two　mesh　layers，the　bearing　capacity　of　the　steel-glass　fiber　mesh　hybrid　slab　is　23.7%　higher　than　that　of　the　slab　of　single　steel　wire　mesh.　Additionally，the　residual　bearing　capacity　at　20　mm　deflection　is　28.2%　higher　than　that　of　the　slab　of　single　glass　fiber　mesh.　The　pre-peak　energy　absorption　values　and　residual　bearing　capacity　at　20　mm　deflection　of　the　hybrid　slabs　of　steel　wire　mesh　and　basalt　fiber　mesh　are　better　than　the　slabs　of　single　basalt　fiber　mesh.　In　the　case　of　three　mesh　layers，compared　with　the　slab　of　a　single　basalt　fiber　mesh，the　energy　absorption　value　of　the　hybrid　slab　with　two　layers　of　steel　wire　mesh　and　one　layer　of　basalt　fiber　mesh　at　2　mm　deflection　is　increased　by　21.6%，and　the　residual　bearing　capacity　at　20　mm　deflection　is　increased　by　42.6%.　The　utilization　rate　of　the　steel-glass　fiber　meshes　hybrid　slab　is　the　most　ideal，and　its　bearing　capacity，energy　absorption　values，and　bending　toughness　index　are　higher　than　those　of　the　steel-basalt　fiber　mesh　hybrid　slab.　Finally，considering　the　effective　utilization　rate　of　mesh　strength，the　bending　capacity　calculation　method　of　meshes　reinforced　UHPC　two-way　slabs　was　established，which　had　good　applicability.　©　2024　Tianjin　University.　All　rights　reserved.
