It used SATWE structure of the space finite element software and a practical engineering structure of beam transfer story of the mechanical behaviors was analyzed. It applied the theories of finite element analysis and dynamic analysis for the reaction rule of structure under vertical static load and wind load and earthquake when the structures were changed the height of the transfer floor or the lateral stiffness ratio.When dynamic elastic time-history analysis was carried and the results of the time-history analysis and response spectrum analysis was compared,we got the effects on seismic behavior of the structure with different height of the transfer floor or the lateral stiffness ratio. It was found after analysis that the higher level of transfer story is,the smaller maximum floor displacement of structure which under vertical static load and the more maximum floor displacement of structure which under
