Description
Technical Field
The invention belongs to the field of civil engineering, and particularly relates to a separated type mild steel damper.
Background
The main energy consumption principle of the mild steel damper is to control the dynamic reaction of the structure through the good hysteresis performance of the metal material after entering the elastic-plastic range. The low-carbon steel has excellent plastic deformation capacity, and can be subjected to reciprocating deformation for hundreds of times under plastic strain which is dozens of times higher than yield strain without fracture, so that the aims of energy consumption and shock absorption are fulfilled in the process.
The elastic-plastic soft steel damper absorbs energy by utilizing the elastic-plastic deformation of steel, and has simple structure and stable performance. The soft steel damper has the advantages of stable hysteresis characteristic, good low-cycle fatigue characteristic, no influence of environmental temperature and the like, so that the soft steel damper has extremely wide application prospect in practical engineering. The traditional mild steel damper adopts a welding mode to fix the steel damping sheet with the upper and lower connecting plates, has the problems of welding residual stress, welding defects, thermal deformation and the like, and has short fatigue life. In addition, the steel damping fin array is arranged and welded on the upper connecting plate and the lower connecting plate, and the problem of insufficient double-sided welding space is caused by undersize gaps of the steel damping fins.
