Analysis of Energy Dissipation Structure of Reinforced Concrete Frame with Additional Metal Damping
The seismic performance curve of single-particle-system is used to investigate the damping amount of additional dampers for reinforced concrete frame structures. The damping amount of the additional metal damper is researched and calculated. First, the original structure is simplified to a single-particle-system. The inter displacement angle of the structure is calculated according to the response spectrum. Then the target interlayer displacement angle of the original structure is set, the damping of the single-particle-system is calculated according to the target interlayer displacement angle. Finally, the damping amount of the multi-particle-system is derived from the damping amount of the single-particle-system, and the damping amount of the additional metal damping required for the multi-particle-system structure is calculated. The time history analysis of seismic response of the calculation model is carried out by Wilson-θ method, and the response value is obtained. At the same time, the hysteretic curve of the damper under earthquake action is drawn, the energy dissipation capacity of the damper is researched by the hysteretic curve. Some considerations are put forward for the design of reinforced concrete energy dissipation frame structures in the future.
