设置粘滞阻尼墙钢框架结构耗能性能试验研究
|
摘要
设计了三榀不同类型的钢框架结构模型,通过对模型的快速水平周期加载试验,进行了设置粘滞阻尼墙钢框架结构减振性能的比较和分析。对设置阻尼墙后钢框架结构的破坏形态、滞回特性、骨架曲线、阻尼力、抗剪刚度、耗能性能、等效阻尼比等进行了研究,对阻尼墙不同布置方式对上述各项性能的影响进行了分析,并对上述各项性能与加载频率、位移幅值的变化关系进行了探讨。结果表明,设置阻尼墙后,钢框架结构的耗能能力和阻尼均有显著提高,结构的抗剪刚度增加,结构的地震响应显著减小。设置阻尼墙钢框架结构的滞回特性与频率、位移幅值相关。阻尼墙不同布置方式对结构滞回特性的影响不明显。
Three different types of steel frame models were designed.By experiments on the steel frame models under lateral dynamic load,the performances of the steel frames with and without viscous damping wall were compared and analyzed.The failure mode,hysteresis loop,skeleton curve,damping force,sheer rigidity,viscous behavior,equivalent damping ratio of the models were studied.The influences of above parameters under difference locations of damping walls were analyzed,and the relations between above parameters and frequencies and displacements were discussed.Experimental study results show that the energy-dissipating capacity,damping force and sheer rigidity can be greatly improved after the installation of viscous damping wall.The seismic response of the frame is obviously decreased.The hysteresis characteristics are relevant to frequency and displacement.The location of the wall has little influence on hysteretic characteristics.
