The invention discloses a transverse damping device applicable to a large-span bridge. The damping device comprises an upper top plate, a lower bottom plate, an upper connecting plate, a U-shaped steel plate, a cushion block, an anchor bolt, a high-strength bolt, bolt holes and a slotting hole, wherein the bolt holes are reserved in the upper top plate and the lower bottom plate, and the upper top plate and the lower bottom plate are respectively and firmly connected with a bridge girder and a bridge tower; the U-shaped steel plate is an energy-consumption element, and is arranged between the upper top plate and the lower bottom plate; the upper connecting plate is reserved with the bolt holes and is fixed below the upper top plate through the anchor bolt; a straight section on the upper part of the U-shaped steel plate is arranged between the upper top plate and the upper connecting plate and is not in contact with the upper top plate; a straight section on the upper part of the U-shaped steel plate is reserved with the bolt hole, the slotting hole is reserved in the upper connecting plate, and the straight section at the upper part of the U-shaped steel plate is connected with the upper connecting plate through the high-strength bolt capable of freely sliding in the slotting hole. According to the damping device provided by the invention, the instant impact force generated in the process of converting the transverse structural system of the large-span bridge can be resisted, and the anti-seismic property of the large-span bridge can be improved.

A negative-stiffness self-adaptive energy-storage anti-shock column used in the fields of construction engineering and protection engineering, comprising an anti-shock outer cylinder, a negative-stiffness self-adaptive unit, an energy storage-energy-dissipation inner cylinder unit and an installation unit. The invention establishes a double anti-shock mechanism, uses the anti-shock outer cylinder as the first anti-shock defense line, uses the negative stiffness adaptive unit to amplify the deformation of the inner cylinder caused by the impact of the outer cylinder, and uses the energy storage-energy consumption inner cylinder to absorb and Enhanced dissipation of impact energy. Through the comprehensive utilization of the negative stiffness adaptive unit set between the inner cylinder and the outer cylinder and the composite energy storage-energy dissipation core material of the inner cylinder, the amplified restoring force and damping force are effectively realized under the action of a very short impact, shortening the The reaction time of the anti-shock column under impact is improved, and the anti-shock efficiency of the anti-shock column is significantly improved. The device of the invention is convenient and flexible to set up, can effectively absorb and dissipate impact energy, has the characteristics of multiple energy storage, high energy consumption, high robustness, and the like, and has good popularization and application value.

The invention discloses a modularized steel pipe concrete multi-dimensional energy-dissipating wall with uniform stress distribution under earthquake, which belongs to the field of anti-seismic technology of assembled structures. The system is composed of prefabricated special-shaped concrete-filled steel tubes, connectors between concrete-filled steel tubes, beam connectors and bolts. The prefabricated special-shaped concrete-filled steel tube is filled with high-performance concrete polymer, which complements the mechanical properties of the external steel tube so that the member has good ductility when it is deformed in-plane and out-of-plane. The energy-dissipating wall adopts distributed walls, and the distributed walls are arranged along the beam direction or perpendicular to the beam direction. When the distributed wall deforms in-plane under the external multi-dimensional excitation, it provides the structure with the ability to resist lateral force; when When the wall deforms out-of-plane, the wall is bent out-of-plane and the stress is evenly distributed at the same thickness, so that the bending energy is dissipated while making full use of the material properties. Each component of the energy-dissipating wall is completely prefabricated by the factory, with controllable quality, and adopts prefabricated modular installation, which is convenient and fast for construction, and can reduce construction period and cost.
