摘要

In this paper, performance of passive viscous and friction dampers subject to near-fault ground motion velocity pulses for elastic and inelastic structures has been investigated through numerical simulations. The objective of the investigation is to determine the guidelines for types of structures where a passive damper may be effective in reducing damages during a near-fault ground motion. Simulation results show that viscous dampers are most effective around T/T_g ≈ 1 for elastic structures, whereas they are most effective for inelastic structures in range of natural periods T/T_g < 1.0 when both the input energy and hysteretic energy (damage) decrease and dissipated viscous energy increases. Passive friction dampers have good performance for elastic structures around T/T_g ≈ 1 where input energy decreases and energy dissipated by the damper increases. For inelastic structures with μ=4, friction dampers have good performance in the range of for 0.3
