In　high-rise　buildings,　reinforced　concrete　(RC)　shear　walls,　particularly　those　forming　part　of　coupled　wall　systems　or　core　wall　systems,　may　be　subjected　to　coupled　axial　tension　and　cyclic　lateral　loads　during　strong　seismic　events.　A　new　two-dimensional　material　model　named　the　＂Fixed　Angle　Model　Considering　Crack　Sliding＂　(FAM-CS)　was　proposed　for　simulating　the　nonlinear　behavior　of　RC　walls　subjected　to　axial　tension　and　cyclic　lateral　loads.　The　proposed　model　was　implemented　in　the　OpenSees　platform.　Nonlinear　constitutive　models　for　shear　aggregate　interlock　effects　of　concrete　and　dowel　action　of　rebars　were　incorporated　into　the　proposed　model　to　represent　the　shear　transfer　mechanisms　along　concrete　cracks.　The　proposed　model　was　validated　against　the　test　data　of　six　wall　specimens　subjected　to　coupled　axial　tension　and　cyclic　lateral　loads.　The　results　indicated　that　the　proposed　model　reasonably　predicted　the　lateral　strength　capacity　(an　average　error　of　6.2　%)　and　the　residual　strength　at　the　maximum　drift　loading　(an　average　error　of　12.3　%)　of　the　specimens.　For　comparison,　three　other　commonly　used　models,　the　Shear-Flexure　Interaction　Multiple-VerticalLine-Element-Model,　the　multi-layer　shell　element　model　and　the　Cyclic　Softened　Membrane　Model　were　adopted　for　the　simulation　of　the　specimens.　Compared　with　the　three　existing　OpenSees　models,　the　newly　implemented　material　model　provided　improved　predictions　of　the　wall　hysteretic　behavior　with　respect　to　lateral　strength　capacity,　lateral　strength　degradation,　pinching　characteristics　and　cyclic　stiffness　degradation.　In　addition,　the　proposed　model　reasonably　captured　the　localized　failure　pattern　as　well　as　the　energy　dissipation　characteristics　of　the　test　specimens.　Finally,　a　mesh　sensitivity　study　was　conducted　to　assess　the　robustness　of　the　proposed　model.　The　results　revealed　that　the　proposed　model　was　robust　regarding　the　lateral　load-drift　responses　of　RC　walls,　with　a　mesh　size　ranging　from　approximately　one　to　three　times　the　average　crack　spacing.
