Abstract:
In view of the fact that the mild steel damper controlling the seismic response might significantly change the natural vibration period of structural system, it is necessary to clarify the effect of the damper on the response spectrum of the non-structural members in the seismic design of the structure. Based on the existing evaluation method of floor response spectrum of elastic structure, considering the influence of periodic ratio of main structure and non-structural components and viscous damping ratio of main structure, the prediction formula of floor response spectrum of viscous damping structure was proposed. The calculation method of the average equivalent stiffness and the average equivalent damping ratio of the nonlinear damping structure system was established. Based on the equivalent linear system, the prediction method of the floor response spectrum of the mild steel damper structure was proposed. The performance curve of the floor response spectrum was obtained to describe the influence of the damper parameters on the acceleration response of the non-structural components. The results show that the equivalent linearization method can be used to predict the floor response spectrum of the non-linear system, and the modified formula can be directly used to estimate the floor response spectrum based on the elastic response spectrum of ground motion and the equivalent parameters of the damping structure. It is applicable for period ratio between 0.5 and 2, and damping ratio between 0.05 and 0.2. This method can be employed to aid structural engineers to choose an optimal damper capacity design considering the response of non-structural components.
