Title:
ASEISMATIC REINFORCEMENT METHOD AND ASEISMATIC REINFORCEMENT STRUCTURE
Document Type and Number:
Japanese Patent JP2019039269
Kind Code:
A
Abstract:
To provide an aseismatic reinforcement technology which facilitates the installation even when there is any factor typical to the existing bridge.SOLUTION: Four bridge girders G1 to G4 are integrated together into one connection girder GX. The constraint in the horizontal direction is reduced with respect to supports B2, B3, B4, B5, B6, and B7 installed in bridge piers P1 to P3. For bridge abutment A1, A2 other than the bridge piers P1 to P3 (the bridge piers which support the supports B2, B3, B4, B5, B6, and B7 to be reduced the constraint in the horizontal direction), the aseismatic reinforcement is applied. More specifically, the aseismatic reinforcement is not given to the bridge piers P1 to P3 for which the construction condition is severe, and the aseismatic reinforcement is given to the bridge abutment A1, A2 for which the construction condition is mild.SELECTED DRAWING: Figure 2
