PURPOSE:To prevent a building from being destroyed by an earthquake by installing a steel frame on an earthquake-proof device set up on the foundation, and fixing a supporting frame, capable of supporting the building when it is shifted as far as the specified distance, onto the foundation in and around the earthquake-proof device. CONSTITUTION:An earthquake-proof device 2 is set up in the important position of a substruction 1 of a wooden building, and a steel frame 3 is installed on this earthquake proof device 2, and furthermore a parallel chord truss 4 is installed between the opposed steel frames 3, forming an earthquake-proof structure. A supporting frame 13, capable of supporting the building when it is shifted as far as more than the specified distance, is fixed on the substructure in and around the earthquake-proof device 2, and thereby a fail-safe mechanism is formed there. With this constitution, since seismic force is absorbed by the earthquake-proof 2, destruction of the building is preventable and, what is more, in case the earthquake-proof device fails to work effectively, the building is safely supportable by the supporting frame 13.
