This paper proposes a novel shape memory alloy (SMA)-friction damper (SFD) which is composed of friction and SMA energy consumption in parallel. Experiments are carried out to demonstrate the effects of the loading frequency, displacement amplitude and number of SMA wires on the hysteretic behavior of the SFD. Experimental results show that the effect of the loading frequency can be negligible, while the energy consumption increases almost linearly with the displacement amplitude. The increment of the number of SMA wires can significantly increase the stiffness and self-centering capacity to improve the performance of the SFD. Then, a numerical model of the SFD is established by the connector and solid elements in ABAQUS. Finally, a beam string structure, a suspend dome structure, K6 and square-pyramid double-layer spherical reticulated shells with and without SFDs under nine ground motions are analyzed by nonlinear dynamic analysis. For the controlled cable supported structures...

形状记忆合金摩擦阻尼器的滞回特性以及电缆支撑结构和网壳的抗震性能评估

本文提出了一种新型的形状记忆合金（SMA）摩擦阻尼器（SFD），该阻尼器由摩擦力和SMA能量消耗并行组成。实验表明，加载频率，位移幅度和SMA导线数量对SFD的滞后行为的影响。实验结果表明，加载频率的影响可以忽略不计，而能量消耗几乎随位移幅度线性增加。SMA导线数量的增加可以显着提高刚度和自定心能力，从而改善SFD的性能。然后，通过ABAQUS中的连接器和实体元素建立SFD的数值模型。最后是梁柱结构，悬浮穹顶结构，通过非线性动力学分析，分析了九种地震作用下有无SFD的K6和方锥双层球面网壳。对于受控电缆支撑的结构...
