借鉴正交试验理论，设计，制作并测试了5个足尺调谐质量型防屈曲支撑试件。影响因素包括工作周期、接触工艺和弹簧布置。其中工作周期3水平，其它因素2水平。重点考察弹簧、接触面摩擦、受力形式等对试件动力性能的影响，以及相关构造条件下 BRB 的性能表现。试验包括自由振动，常见地震烈度条件下共振试验和静力拉压试验。研究分析了试件频谱特性，动力系数和阻尼比变化规律，拉压滞回性能。试验结果表明，对称弹簧布置的轮式构造试件调谐精度高，TMD 特性明显，BRB 相关性能指标能够满足行业规定，实现复合减震功能在构造上的“兼顾”。

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.
