Finite Element Analysis of Corrugated Mild Steel Damper

A new kind of mild steel damper which use corrugated plate as energy-intensive steel plate is proposed in this paper. The structures and energy dissipation principles of the new type damper are presented. The hysteretic performances of corrugated mild steel damper with different height-thickness ratio, or with the same height-thickness ratio but with different thickness are analysed by numerical simulation with ABAQUS platform and then parameter study on this kind of damper in detail. The results show that the corrugated steel damper has good and stable energy dissipation performance. The performance of energy consumption increases with the decreasing of height-thickness ratio. When at the same height-thickness ratio, the performance of energy consumption increases with the thickness of energy-intensive steel plate.
