Abstract

The invention discloses a reinforcement device for a simply supported girder bridge, and relates to the technical field of bridge engineering. The reinforcement device comprises a fixed support and a movable support, wherein a girder bridge is arranged between the fixed support and the movable support; a plurality of supporting columns are arranged between a hinged support and the movable support; the supporting columns extend to the lower part of the girder bridge from the ground; network supporting frames are arranged between each supporting column and the hinged support, between the supporting columns and between the supporting column and the movable support; supporting surfaces matched with the lower part of the girder bridge are arranged on the network supporting frames. Compared with the prior art, the reinforcement device provided by the invention can enhance the strength of the simply supported girder bridge.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a reinforcement device for a simply supported girder bridge which improves the seismic capacity of the girder bridge. Background technique [0002] A simply supported beam bridge is a beam bridge whose main load-bearing structure is a beam whose two ends are respectively supported on a movable support and a fixed hinge support. It belongs to a statically determinate structure. Under normal circumstances, the bridge will not have rigid body displacement, but under the action of internal force, the end of the movable support can deform freely, so no redundant secondary internal force will be generated. In the case of simple structure and convenient erection, the structural internal force of this type of bridge will not be affected by foundation deformation and temperature changes. [0003] But it is also because of this structure that the simply supported girder bridge ...
