Title:
SEISMIC STRENGTHENING DEVICE
Document Type and Number:
Japanese Patent JP2016079760
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve aseismic performance of a rigid-frame structure while reducing the number of reinforcement points without placing a burden on a foundation.SOLUTION: A seismic strengthening device 40 comprises: a vertical member 4 which is vertically installed along at least any one of columns 20 constituting a rigid-frame structure; and energy absorbing mechanisms 3 which are respectively installed between upper sections 20 and 30 of the rigid-frame structure and an upper edge of the vertical member 4 and between lower sections 10 and 20 of the rigid-frame structure and a lower edge of the vertical member 4. The energy absorbing mechanisms 3 are adapted to absorb energy which causes the vertical member 4 to incline by elastically deforming with an inclination of the vertical member 4 to a horizontal plane when the rigid-frame structure oscillates in a manner that displaces the upper sections 20 and 30 of the rigid-frame structure in a horizontal direction with respect to the lower sections 10 and 20 thereof.SELECTED DRAWING: Figure 2
