Abstract: Introduced the working principle of planar movable stereo garage,analyzed the advantages and disadvantages of the existing planar movable stereo garage.Researched and put forward the structure scheme of a new type of high level planar movable stereo garage,introduced the structure form of car carrying board,conveying trolleys,automobile rotary disk and elevating platform,expounded the principle of parking and taking car of high level planar movable stereo garage.When considered in three conditions of wind load,earthquake and earthquake with wind load,steel structures were static analyzed and dynamic analyzed by using finite element analysis software ANSYS Workbench to get the deformation and the stress.Compared with the safety factor and allowable stress of the steel structure to verify the overall stability of the steel structure scheme.

Key words: planar movable stereo garage, ANSYS Workbench, dynamic analysis, the safety factor and allowable stress, stability
