To　study　the　bearing　capacity　of　the　steel　plate　concrete　composite　wall　and　the　effect　of　design　parameters　on　the　bearing　capacity,　finite　element　analysis　is　performed　to　simulate　the　steel　plate　concrete　composite　wall　using　ABAQUS,　based　on　the　experiment　of　4　steel　plate　concrete　composite　wall　for　nuclear　power　engineering.　Concrete,　steel　plate　and　stud　are　simulated　by　solid　models.　The　nonlinear　behavior　of　materials　and　residual　stress　of　welded　steel　plate　are　taken　into　account　in　the　analysis.　The　stress　mechanism　of　stud　is　investigated,　and　the　buckling　deformation　of　steel　plate　is　simulated.　Various　parameters　are　investigated,　such　as　the　strength　of　the　steel　and　concrete,　distance　to　thickness　ratio,　steel　content　that　effects　the　bearing　capacity.　The　results　of　finite　element　analysis　are　found　to　be　in　good　agreement　with　the　experimental　results;　the　stud　are　always　in　the　elastic　stress　state;　concrete　strength　has　biggest　influence　on　the　bearing　capacity;　the　distance　to　thickness　ratio　has　great　effect　on　the　buckling　of　steel　plates,　and　smaller　ratio　of　distance　to　thickness　can　ensure　steel　plate　and　concrete　cooperative　work.　©　2016,　Engineering　Mechanics　Press.　All　right　reserved.
