- Abstract:
- Taking the single degree of freedom system as an example, the difference between the traditional structure and the structure with additional energy consuming devices was analyzed from the perspective of structural mechanics and energy, and the principle of energy dissipation structure was obtained. Various types of dampers were simply summarized and classified from different angles such as energy consuming materials, energy consumption mechanism, and force form. Several typical soft steel dampers at home and abroad were summarized, such as X-shaped dampers, triangular dampers, diamondshaped opening dampers, circular dampers, etc. The brief descriptions of the proposed, development, optimization, geometric structure and damping principle of these kinds of mild steel dampers were given. Aiming at many problems that need to be solved for the energy dissipation structure using damper energy dissipation, several problems to be solved in the damper research and some suggestions that can be taken in the future damper design were proposed. The results show that the energy dissipation structure is more effective than the traditional structure under the same seismic force, such as increasing the energy consumption of the damper, reducing the plastic deformation energy consumption and hysteretic energy consumption of the original structure, thereby reducing the damage of the main structure. The soft steel damper is the most common research and application due to its simple structure, stable mechanical performance, relatively low cost and remarkable energy consumption. The damper design should consider the reasonable plane shape, set up multiple energy consuming components and energy consumption mechanism, use new materials and new technologies to reduce solder joints, establish more accurate constitutive relationships and more complete guidelines.
