In　order　to　perfect　the　method　to　analyze　the　steel-concrete　hybrid　structures　system,　according　to　the　cooperating　model　of　the　frame-shear　wall　structures,　and　based　on　two-dimensional　elastic-plastic　analysis　model　and　the　corresponding　calculation　method　to　analyze　the　seismic　response　of　the　steel　frame-concrete　tube　hybrid　structures,　a　pseudo-three-dimension　elastic-plastic　seismic　response　analysis　method　is　established,　considering　the　vertical　spatial　restrain　effects　of　the　transverse　beam　between　steel　frame　and　concrete　tube.　It　can　simulate　the　spatial　restrain　effects　between　steel　frame　and　concrete　tube　simply.　Then,　a　case　is　analyzed　by　using　the　pseudo-three-dimension　analysis　method　which　considered　the　vertical　spatial　restrain.
