Figure 3

Simulation results for the SDOF model (𝑓_𝑛=0.25 Hz; 𝜉=10%) with a passive damper. (a) Evolution of responses versus passive device damping for 10 type 1 seismic actions and the correspondent mean curve; (b) damping coefficients (for 𝛼=0.15) for the minimum mean peak acceleration response function of system natural frequencies under type 1 and 2 seismic actions.
