Released energy due to tectonic events will be absorbed by structural elements when an earthquake occurs, and cause destruction. In order to reduce structural damage, input energy must be dissipated. Yielding elements will act as fuse and absorb a great deal of earthquake input energy. Two one-story steel frames with different bay to height ratios (B/H<1 & B/H>1) are investigated in this article. First, by studying of the elastic behavior of system best location of ring with various percentages of openings is proposed. Then, different angles for ring elements connection are tested in each location. The stiffness ratio of steel frames to a similar moment frame without any braces is used as a criterion for comparing different locations and angles. After that, Nonlinear dynamic response of frame subjected to different ground motion records is obtained, and largest displacement and most base shear of different frames are compared. Finally, the ratio of dissipated energy by yielding elements to total entering energy of structure was calculated. This ratio shall assist designer toward better judgment for using this kind of yielding elements between energy dissipater systems.
