Little-character-toggle-brace-damper seffsmffc energy dissepation systems

The application of seismic energy dissipation systems is increasing in many countries. This paper presents one new configuration called little-character-toggle-brace. It takes a little room because of lying on the top of the story, and moreover, it utilizes toggle-brace mechanisms to substantially magnify the effect of damping device, so that it can be installed expediently and applied in small structural drift. This paper analyses,the effect of different toggle-brace position in the story and different angle of the toggle-brace to the magnification factor and provides the force in the little-character-toggle-brace-damper and damping radio of the structure. In order to compare the effect of the structure installed the little-character-toggle-brace with the little-character, the diagonal or chevron energy dissipation brace, dynamic response-history analysis of the structure installed separately these four kinds of energy dissipation braces has been conducted using the computer code Sap2000.
