Can make full use of land resources of mechanical parking equipment, flexible layout, high efficiency and energy saving, is now one of the important ways to solve the problem of parking difficulty, among them three-dimensional garage for lifting and moving type most widely used. This topic was typical to lift move transversely type parking equipment as the research object, and steel structure of garage design and finite element analysis. Combining with the actual engineering projects, the four layers of three-dimensional garage for lifting and moving type steel structure design. Stereo garage steel structure design including the garage overall scheme, the selection of the overall size to determine, column, beam and girder design, connectiondesign, etc. First of all, according to the construction site garage space limitation and the lower the design requirement and main body frameworks overall size; After the column, beam, longitudinal beam, connection design and str
