Combined ultra-elastic overlapping multi-bending-plate vibration reduction energy consumption device for self anchoring suspension cable bridge

Abstract

The invention discloses a combined ultra-elastic overlapping multi-bending-plate vibration reduction energy consumption device for a self anchoring suspension cable bridge. The device is the combined ultra-elastic overlapping multi-bending-plate vibration reduction energy consumption device; certain energy consumption capability is realized in earth quake or under the condition of normal load, so that the bridge damage degree can be reduced; the device belongs to the technical field of shock resistance and shock reduction. The device is applied to the self anchoring suspension cable bridge, and can meet the carrying force and intensity requirements under the power load effects of the normal wind load, vehicle running, braking and the like; certain energy consumption capability is realized; the energy consumption can be realized in great earthquake; along with the external stimulation increase, the device can generate the ultra-elastic deformation; the integral effective rigidity of the self anchoring suspension cable bridge is effectively improved. Therefore the problem that a reinforcing beam of the self anchoring suspension cable bridge bears great axial pressure is solved.

Description

technical field [0001] The invention relates to a combined structure that can not only realize the energy dissipation capacity but also improve the rigidity of the main girder of the suspension bridge on the self-anchored suspension bridge, which can meet the requirements of bearing capacity and strength structure in the normal state of wind, driving and braking , has sufficient energy dissipation performance in earthquakes, and can provide sufficient stiffness to the stiffening girder (main girder) of the suspension bridge under rare earthquakes, slowing down the damage of the self-anchored suspension bridge, which belongs to the wind resistance, earthquake resistance and The field of shock absorption technology. Background technique [0002] In recent years, due to the frequent occurrence of earthquakes and other natural disasters, there has also been a huge threat to the bridge. When an earthquake occurs, as the seismic wave propagates to the foundation, the bridge found...
