| 摘 要： | 对空框架以及附加单向斜撑、小八字撑、小八字曲拐撑的4种结构进行自由振动试验和正弦稳态激振试验,比较这4种消能支撑的消能能力.在正弦稳态激振试验中,分别对这4种结构施加不同的柱端位移,测试其在不同频率下框架及阻尼器的力-位移滞回曲线,并进行比较分析.结果表明:附加粘弹性消能支撑后,结构整体刚度改变不大,阻尼有所增大;框架结构本身的消能能力有限;与单向斜撑和小八字撑相比,小八字曲拐撑有着较好的消能能力,更为有效地保护主体结构在地震中免遭破坏.

| Abstract: | The natural vibration experiment and steady-state sinusoidal excitation experiment of the frames without energy dissipation braces and those with attached energy dissipation brace in forms of single inclined brace,double inclined braces,and double inclined toggle-braces were introduced,and their capability of energy dissipation was compared to each other.In the latter experiment,different displacements were applied to the column end,the force-displacement hysteresis curves of the frames and their viscoelast... |
