The Stability

To the H-shaped Mild steel damper which has been applied to the market, this paper proposes the opening box dampers were made in material Q235 steel. Studied the influence of the angular size between Webs and vertical direction to the box-shaped Mild steel damper by FEM ABAQUS. The results indicated that under the same rate in the web openings, box dampers has the same yield displacement and hysteresis curves were fuller than H-shaped dampers. With the increase of web and vertical angles, the initial stiffness of the damper box steel and yield strength and yield stiffness of the damper would reduced, but all of these are larger than H-shaped steel dampers; Meanwhile, moment of inertia of box dampers’ two webs to Y-axis is larger , which greatly enhancing the stability of the outside plane to the damper, the larger Web angles, the stronger yield strength and the stability of the outside plane.

The Impact

In order to improve the energy consumption capacity of the assembled self-resetting pier, the mild steel damper is added to the prefabricated self-resetting pier to form a prefabricated self- resetting pier with an external mild steel damper. Two sets of pier models were established by numerical simulation. On the basis of verifying the correctness of the traditional prefabricated self- resetting pier model, the two sets of pier models were subjected to low-cycle reciprocating loading to study the influence of the mild steel damper yield strength parameters and the pier axial compression ratio parameters on the seismic performance of the pier structure. The results show that compared with traditional prefabricated self-resetting piers, the hysteresis curve of self-resetting piers with mild steel dampers is fuller, and energy consumption and bearing capacity are greatly improved. With the increase of the yield strength of the mild steel damper, the energy consumption capacity will decrease when the loading displacement is less than 25mm, but the overall energy consumption capacity will increase. As the axial compression ratio of the pier column increases, the bearing capacity and energy consumption capacity of the structure increase significantly, but the impact is not obvious when the axial compression ratio exceeds 0.052.

Different Thickness

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.
