Damage controllable and seismic damage repairable steel column
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.
