N2 - This paper aims to evaluate the vibration property of a two-story timber structure which has energy dissipation devices to enhance the seismic performance. Oil dampers and friction dampers are considered as the energy dissipation devices in this study. Steady-state response of a two-degree-of-freedom system which has the nonlinear springs with the force-deformation relation of timber structure and the dampers is derived by using the equivalent linearization technique and the sequential quadratic programming. Through the comparison of the resonance curves of the models with/without dampers, it is found that the friction damper reduces the story drift mainly around the first mode while the oil damper works to decrease the story drift both around the first and the second modes.
