摘要
提出了一种带U形板钢阻尼器,对其进行拟静力试验,考察力学性能。试验结果表明:这种阻尼器在往复荷载作用下能屈服而不发生屈曲,表现出良好且稳定的承载力;滞回曲线饱满,等效阻尼比可达0.494,因此具有良好的耗能能力。在有限元软件ABAQUS中建立了精细化的有限元模型,对模型进行了分析,所建立的有限元分析模型能够很好地模拟该阻尼器的力学行为。
A new damper with U-shaped steel plates was developed in the research. The quasi-static test was carried out on the damper to verify its mechanical properties. The test results showed that the new damper could yield without buckling under cycle loading. The hysteretic curves of the damper was stable. The equivalent viscous damping ratio was up to 0. 494,which showed the favorable energy-dissipating capacity of the damper. Moreover,a refined model of the damper was developed and analyzed by using ABAQUS to simulate the mechanical properties of the damper.
