The basic difference between the moving house ande the tradition house is to being assembled(dismounted) convenient rapidly, mall after dismounting,easy to transport and store,used repeatedly,low request to the field and simple base setting, therefore in such as life, military fields the structures has extensive applications. The moving house studied in this paper, is developed by constructional engineering research institute of the Liberation Army’s logisrics department. It’s the first time to be debeloped in the nation and there are no special design computing methods and rules, relevant research is less too. Therefore the research on the moving aluminum alloy house takes on very important significance in theory and application.In this article, in allusion to the service condition and feature of the Light Aluminum Alloy Mobile Building, our create the finite element model of the framework and holistic structures, the modal analysis of the Light Aluminum Alloy Mobile Building Structure’s framework and holistic have been analyzed with the iterative method of sub-space, on the basis of this,with the method of time-history analysis, calculate the structural dynamic analysis in the design of intensity 70 when the frequent and rare earthquake under the level of seismic waves, vertical seismic waves, two-way seismic waves and three-way seismic waves , through calculation and analysis ,get the structure’s response level and mechanical behavior,and overall merit the structure’s dynamic resistant capacity,all the work offers theorecital warrant for proper using of activity room.
