PROBLEM TO BE SOLVED: To provide a vibration control structure of an automatic warehouse which can prevent articles stored on racks from tipping and dropping in the event of an earthquake and which can be easily repaired after an earthquake, while securing the stability of a building after damage caused by a severe earthquake. SOLUTION: For a frame which undergoes bending deformation in response to an earthquake and receives alternate positive and negative axial forces on its columns, all or some of the columns subject to the alternate positive and negative axial forces have their lower parts constructed of members 10 which yield under lower load than other members. Columns made of steel with a very low yield point, or steel dampers, are used as the members 10. COPYRIGHT: (C)2004,JPO
