This　paper　proposes　an　innovative　method　to　calculate　the　normal　stress　of　concrete　slabs　near　the　intermediate　support　for　composite　girder　bridges　with　corrugated　steel　webs　(CSWs).　The　shear　stiffness　of　CSWs　is　lower　than　that　of　concrete　webs,　which　will　lead　to　significant　shear　deformation.　For　composite　girders　near　intermediate　supports,　the　shear　deformation　of　CSWs　will　be　constrained　by　the　crossbeam,　resulting　in　additional　stresses　in　the　top　and　bottom　concrete　slabs.　The　constrained　effect　of　the　shear　deformation　is　not　considered　in　most　design　codes,　which　will　lead　to　unsafe　designs.　Therefore,　analytical　solutions　of　the　concrete　normal　stress　under　different　boundary　and　load　conditions　were　derived　based　on　the　elastic　bending　theory　considering　the　shear　deformation　of　the　CSWs.　Experimental　analysis　and　finite-element　analysis　(FEA)　were　carried　out　to　further　validate　the　analytical　solutions.　The　results　show　that　the　proposed　analytical　equations　can　be　used　to　accurately　predict　the　normal　stress　of　concrete　slabs.　The　additional　stress　exists　in　the　concrete　slabs　near　the　intermediate　supports,　and　the　plane-section　assumption　is　not　applicable　in　this　area.　The　value　of　the　additional　stress　decreases　to　zero　with　the　increase　of　the　distance　from　the　fixed　end.　The　additional　stress　is　in　the　same　direction　as　the　general　bending　stress　at　the　upper　edge　of　the　top　concrete　slab　and　the　lower　edge　of　the　bottom　concrete　slab,　which　will　increase　the　peak　tensile　and　compressive　stress　of　the　whole　section.　Finally,　a　practical　simplified　calculation　method　of　the　concrete　normal　stress　near　the　intermediate　supports　is　proposed,　and　the　calculation　procedure　is　plotted.　All　the　findings　can　be　used　for　the　design　of　composite　girder　bridges　with　CSWs.
