REINFORCING STRUCTURE FOR STEEL RIGID-FRAME BRIDGE PIER

Title:

REINFORCING STRUCTURE FOR STEEL RIGID-FRAME BRIDGE PIER

Document Type and Number:

Japanese Patent JP2003049404

Kind Code:

A

Abstract:

To provide reinforcing structure exhibiting a deformation restraining effect besides a stress reducing effect, easily constructed and adjustable comforming to a construction site by quantifying the effect in the structure for reinforcing a joint part of structural members such as a column and a beam in a steel rigid-frame bridge pier.

A corner part formed by the column 2 and the beam 3 of the steel rigid-frame bridge pier 1 is provided with reinforcing devices 10 on both edge sides in the cross direction of flanges 2a, 3a. The reinforcing device is provided with a pair of anchor members 12 installed at the column 2 and the beam 3 respectively, and a prestressed concrete steel cable 11 (prestressing tendon) stretched in a tensed state between a pair of anchor members 12. This prestressed concrete steel cable 11 can by-pass the flow of force transmitted from the column 2 to the beam 3 or from the beam 3 to the column 2.
