In　order　to　evaluate　the　shear　performance　and　establish　shear　capacity　formula　of　L-shaped　steel　plate　reinforced　concrete　shear　wall，a　nonlinear　finite　element　model　was　established　and　verified　by　using　the　experimental　results.　Additionally，the　effects　of　height-width　ratio，axial　compression　ratio，steel　plate　thickness，concrete　strength　and　flange　length　on　the　shear　performance　of　the　shear　wall　were　studied.　Finally，the　shear　capacity　formula　of　the　shear　wall　was　proposed.　The　results　indicate　the　web　is　the　main　bearing　component　of　the　shear　wall.　With　the　decrease　of　height-width　ratio，the　shear　capacity　and　initial　lateral　stiffness　of　shear　wall　increase.　The　shear　capacity　of　the　shear　wall　increases　with　the　increase　of　axial　compression　ratio，but　the　shear　capacity　begins　to　decrease　when　the　axial　compression　ratio　exceeds　0.5.　The　shear　capacity　formula　of　the　shear　wall　proposed　in　this　paper　has　a　small　discrepancy　as　compared　with　the　existing　formula，which　can　provide　a　reference　for　the　future　engineering　applications.　©　2024　Tongji　University.　All　rights　reserved.
