The beam falling is the most serious seismic damage phenomenon of the bridge, and the largest destructiveness, the highest repair difficulty and the largest harmfulness can be found from the seismic damage investigation of the bridge in the past. To avoid the occurrence of beam drop, many beam drop prevention measures have been proposed. The conventional limiting and beam falling prevention measures can prevent the beam falling to a certain extent, but the common limiting device can be damaged and fail under the action of a great earthquake, so that the beam body is prevented from falling due to the loss of necessary constraint.
In the face of severe earthquake-resistant situation, the bridge anti-falling beam structure should have more reliable force transmission mechanism and supporting conditions. The development of a novel limiting anti-falling beam structure which is simple in structure, reliable in force transmission and remarkable in effect is urgently needed, so that the earthquake risk can be effectively resisted, and the occurrence of beam falling can be prevented to the maximum extent.
