In　base-isolated　tall　shear　wall　buildings,　the　bidirectional　anti-pulling　sliding　device　is　used　to　resist　tension　and　bear　pressure.　In　this　paper,　it　was　developed　and　used　together　with　the　laminated　rubber　bearing　to　form　a　composite　base-isolation　system.　Based　on　the　established　dynamic　mechanical　model　of　this　base-isolated　system,　the　frequency　equation,　mode　orthogonal　conditions,　generalized　mass　and　stiffness　were　deduced.　According　to　the　Hamilton　principle,　the　equivalent　damping　ratio　in　each　mode　produced　by　the　damping　of　laminated　rubber　bearings　was　derived.　Therefore,　the　seismic　response　of　base-isolated　tall　shear　wall　buildings　can　be　solved　by　the　modal　superposition　method.　The　seismic　response　of　a　sixteen-story　base-isolated　shear　wall　building　was　obtained　by　establishing　a　dynamic　model　and　carrying　out　analysis　against　that　model,　demonstrating　that　this　composite　isolated　system　has　an　obvious　function　of　shock　absorption,　thus　the　bidirectional　anti-pulling　sliding　device　can　resist　tension　produced　by　over-turning　moment.　In　addition,　the　seismic　response　obtained　through　the　established　dynamic　model　in　this　paper　was　basically　consistent　with　that　by　numerical　integration　solution　of　FEM,　showing　the　correctness　of　the　established　dynamic　model　and　the　solving　method.
