This　paper　presents　experimental　and　numerical　studies　on　the　lateral　performance　of　midply　wood　shear　walls.　A　kind　of　anchor　tie-down　system　(ATS)　is　introduced　into　the　wood　shear　wall,　and　two　different　wall-foundation　connections　(i.e.,　screwed　connection　and　bolted　connection)　are　considered.　Reserved　cyclic　loading　tests　were　conducted　to　investigate　the　failure　modes,　lateral　load　resisting　capacity,　stiffness　degradation,　and　energy　dissipation　of　four　midply　wood　shear　wall　specimens.　Test　results　show　that　with　the　installation　of　ATS,　the　lateral　load　resisting　capacity,　energy　dissipation,　and　lateral　stiffness　of　the　specimen　increased　by　154%,　427%,　and　93%,　respectively.　The　pull-out　failure　of　the　wall　studs　was　also　avoided　with　the　application　of　ATS.　Compared　with　the　midply　wood　shear　wall　specimens　with　bolted　wall-foundation　connection,　the　specimens　with　screwed　wall-foundation　connection　dissipated　more　energy;　however,　the　fatigue　failure　of　the　screws　might　lead　to　brittle　failure　of　the　shear　wall.　A　nonlinear　finite　element　model　of　the　midply　wood　shear　wall　was　then　developed　and　verified　with　the　test　results.　User-defined　Q-pinch　model　was　applied　to　simulate　the　sheathing-framing　connection　of　the　shear　wall.　The　simulation　results　show　that　the　hysteretic　behavior　of　the　specimen　with　ATS　was　well　predicted.　The　experimental　and　numerical　studies　provide　fundamental　knowledge　for　the　development　and　application　of　midply　wood　shear　walls,　especially　for　the　application　of　such　wall　system　into　mid-rise　timber　structures.　(C)　2019　Elsevier　Ltd.　All　rights　reserved.
