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/Tg ≈ 1 for elastic structures, whereas they are most effective for inelastic structures in range of natural periods T/Tg < 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/Tg ≈ 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 <T/Tg <2.
