O型钢板-高阻尼黏弹性复合型消能器的力学性能试验与分析
|
摘要
提出了一种由O型钢板金属阻尼器与高阻尼黏弹性阻尼器并联而成的复合型消能器,阐述了其构造形式和工作机理,对其进行了低周反复加载试验。研究结果表明:复合型消能器具有较强的变形能力和饱满的滞回曲线;其力学性能稳定,受加载频率影响较小;该消能器兼具位移型阻尼器与速度型阻尼器的优点,小变形时,黏弹性阻尼器发挥主要的耗能作用,O型钢板金属阻尼器提供一定的附加刚度,大变形时,二者共同耗能;相比单一类型的消能器,该复合型消能器提高了阻尼力和抗震安全储备;采用Bouc-Wen模型建立了该消能器的力学模型,计算结果与试验结果吻合较好。
A new composite energy dissipator made of two O-shaped steel plate metal dampers and one high damping viscoelastic damper was developed.The construction details and working mechanisms were introduced.Cyclic loading tests on the dissipator were carried out.The test results show that the composite energy dissipator possesses a large deformation capability and a full hysteresis curve.The mechanical properties of the dissipator are stable and insensitive to loading frequencies.It has the advantages of the velocity-dependent damper and displacement-dependent damper.When the deformation is small,the viscoelastic damper plays the major role in energy dissipation,and the O-shaped steel plate metal dampers contribute to stiffness.When the deformation is large,two types of dampers dissipate the seismic energy together.Compared with the dampers of a single type,the composite energy dissipator offers a much larger damping force and seismic safety margin.The calculation model for the composite dissipator was established by using the Bouc-Wen model.The calculation results were in good agreement with experimental results.
