Seismic behavior of special moment-resisting frames with energy dissipating devices under near source ground motions
Mahmoud Bayat and Mahdi Bayat

Abstract     [Full Text]
    In this study, the performances of the SMRF building equipped with energy dissipating devices are studied. Three types of these structures with different heights are considered. The Added Damping and Stiffness (ADAS) devices are used as energy dissipating devices in these structures. The behavior of these structures with ADAS devices subjected to near source ground motions are investigated. Three SMRF buildings with five, ten and fifteen-story, with ADAS devices were chosen. The nonlinear time history analysis was used by applying the near source ground motions with PERFORM 3D.V4 and conclusions are drawn upon an energy criterion. The effect of PGA variation and height of the frames are also considered based on the energy criterion.
Key Words
    Dampers (ADAS); SMRF frame; energy dissipation devices; near source ground motion
