Damping energy dissipation device and epsilon-shaped steel structure thereof

Abstract

The invention discloses an epsilon-shaped steel structure of a damping energy dissipation device, which is characterized in that the epsilon-shaped steel structure comprises a first arc section and a second arc section which are abreast arranged, the opening directions of the first arc section and the second arc section are consistent, and one end of the first arc section and one end of the second arc section are intersected to form an integral structure; and the other end of the first arc section and the other end of the second arc section are fixed ends, the fixed end of the first arc section and the fixed end of the second arc section are respectively hinged with the fixed parts of the damping energy dissipation device, the ends of the first arc section and the second arc section which intersected with each other are movable ends, and the movable ends are hinged with the movable parts of the damping energy dissipation device. By adopting the arrangement, the epsilon-shaped steel structure can effectively improve the damping energy dissipation effect of the damping energy dissipation device on the premise that the limit to the installation of the damping energy dissipation device is ensured to be small. The invention additionally discloses the damping energy dissipation device with the epsilon-shaped steel structure.

Description

technical field [0001] The invention relates to the technical field of bridge anti-seismic structures, in particular to a damping energy dissipation device and an ε-shaped steel structure thereof. Background technique [0002] The bridge is a pivotal project of transportation. Once it collapses, it will cause huge losses to people's lives and properties. Therefore, bridges are also the transportation facilities with the highest technical requirements and quality requirements among all transportation infrastructures. [0003] In the major earthquakes that occur around the world, bridge facilities bear the brunt. Bridge facilities are easy to be damaged, and bridge damage will lead to traffic blockage, which is likely to cause more serious secondary disasters. Therefore, anti-seismic measures must be adopted for bridges in earthquake areas to ensure that the bridges can still be used normally after the earthquake. [0004] At present, elastic-plastic steel structures are wi...

Problems solved by technology

[0005] However, C-shaped steel is limited by its own structure, the damping force is small, and the energy dissipation effect is poor; E-shaped steel has a large volume, and its installation is more restricted.
