Abstract: A container building is a type of typical off-site construction building that is remodeled from containers used for shipping and cargo transportation，which features industrialization and fast construction． Container buildings are different from common buildings． Software for container buildings design does not exist． FE software is not convenient for container building design． A corrugated panel of containers was regarded as steel plate shear wall． Initial stiffness and yielding capacity of the corrugated panel were calculated by FE analysis． Under equivalent principle of stiffness and loading capacity，the corrugated panel was simplified into a crossed brace． Then by employing common structural design software，a container building was designed．
