摘要:

Using the orthogonal test theory, five full sized tuning mass damped buckling-restrained brace (TMD-BRB) specimens were designed, manufactured and tested. The influence factors included work period, contact surface craft and springs layout. There were 3 levels for work period and 2 levels for the other two. The effects of spring, friction between contact surfaces and force form on the dynamic behavior of specimens were investigated in detail. In addition, the performance of BRBs in the related structures was tested. The tests included free vibration, resonance tests under common seismic intensity and cyclic static tests. Spectral characteristics of specimens, change laws of dynamic coefficients and damping ratios, and hysteretic curves were analyzed. The results showed that the specimens with symmetrical springs and wheels have a high tuning precision, strong TMD properties and standard index for BRB performance to realize a structural balance between composite vibration reduction functions.
