Embodiment 1

[0019] see Figure 1 to Figure 2 As shown, a damage-controllable and repairable steel column of the present invention is characterized in that it includes: a steel column 1, a damper 4, and a first connecting plate 5; the first connecting plate 4 is fixed on the cap Above, the steel column 1 is connected to the first connecting plate 5 through a damper 4; the damper 4 includes a plurality of detachable soft steel plates, and the soft steel plates are placed vertically.

[0020] Furthermore, the steel column 1 is fixed to the platform through the end plate 2-1, and transmits the axial force generated under the action of the vertical load.

[0021] Furthermore, the outer side of the steel column 1 is provided with a plurality of connecting plates 3 connected to the plurality of mild steel plates of the damper 4; Face vertical.

[0022] Furthermore, the mild steel plate of the damper 4 is detachably connected to the connecting plate 3 through friction-type high-strength bolts. ...

Embodiment 2

[0027] The steel column 1 is a square column; the four side panels of the steel column are connected to the first connecting plate through dampers.

[0028] In this embodiment, the steel column 1 is a square column. The end plate 2-1 is connected to the bearing platform, the steel column 1 includes four side panels, and the four side steel plates are welded to the end plate 2-1. In this embodiment, the side of the steel column 1 facing the T-shaped connecting plate is the outer side.

[0029] Each side panel of the steel column 1 corresponds to the T-shaped connecting plate, and the outer side of the steel column 1 is provided with a connecting plate 3, and each side steel plate of the steel column 1 is connected with the corresponding T-shaped connecting plate. There are four dampers 4, that is, there are four dampers 4, and the number of soft steel plates for each damper 4 is calculated according to actual needs.

[0030] The mild steel plate on the damper 4 is detachable ...

Abstract

The invention discloses a damage controllable and seismic damage repairable steel column, comprising a steel column, dampers and first connecting plates. The steel column is connected with a bearing platform through end plates. The first connecting plates are fixed on the bearing platform. The steel column is connected with the first connecting plates through the dampers. Each damper comprises a plurality of demountable soft steel plates which are vertically placed. In the case of a small earthquake, the steel column and the dampers co-act and both the steel column and the dampers are elastic; in the case of a strong earthquake, with relatively good plasticity, the soft steel plates serving as energy-dissipating plates of the dampers can generate shearing yield, thereby absorbing most of earthquake energy, well protecting the steel column from being damaged and ensuring good aseismic performance; meanwhile, as the soft steel plates are demountable, after the strong earthquake, the damaged soft steel plates can be replaced with complete soft steel plates to provide post-earthquake quick repair.

Description

technical field [0001] The invention relates to an anti-seismic structure of a steel column, which is a steel column whose damaged part can be controlled under the earthquake and can be quickly repaired after the earthquake. Background technique [0002] The intelligentization and sustainability of urban development pose new requirements and challenges to the industrialization of buildings and seismic structures of engineering structures. Among them, the rapid repair of structural earthquake damage and the rapid recovery of building functions are the basic requirements and important aspects of "recoverable functional cities". research direction. Recoverable performance structures generally refer to building structures that can recover their performance without repair or moderate repair after the structure encounters an earthquake. The research and development, promotion and application of restorable performance structures can not only significantly reduce direct earthquake d...
