A　diagonal　bracing　frame　model　was　put　forward　to　analyze　short　pier　shear　wall　with　concealed　bracings.　Geometry　characteristic　and　a　parameter　defining　method　were　developed　for　the　model　and　the　stiffness　matrix　was　deduced.　The　reasonable　force-displacement　relationship　of　the　frame　element　was　selected.　Push　over　analysis　using　the　diagonal　bracing　frame　model　was　carried　out　on　two　short　pier　shear　walls　and　the　calculating　results　indicate　that　the　model　is　reasonable.
