Structure and Vibration-reduction Study on Tuning Mass Dampered-buckling Restrained Brace(Ⅰ)

For the composite functions of BRB implementation, SRC tube confining the steel core designed as a TMD mass, the core taken as the sliding track, and additional springs added as resilient elements, a new type damper called Tuning Mass Dampered-Buckling Restrained Brace (TMD-BRB) was studied.Resultsshow that it has no affect on the working frequency by slant setting for the component. The TMD dynamic coefficient affects by amplitude, working period and vibration frequency.The contact friction coefficient should be controlled below 0. 3. Sliding tests and FEM analysis show that it has a high dynamic coefficient and a stable hysteresis performance by this recommended construction.
