自复位双肢剪切型耗能段的滞回性能与力学模型
Hysteretic Performance and Mechanical Model for An Innovative Self-Centering Coupled Shear Link
基于双肢短剪切型耗能段的耗能机制、形状记忆合金(shape memory alloy, SMA)棒材的超弹性特性和碟形弹簧的恢复力特性,提出了一种自复位双肢剪切型耗能段(self-centering coupled shear link, SC-CSL),该耗能段可有效提高中心支撑钢框架结构的抗震性能和震后恢复能力。采用校正的有限元法对SC-CSL的力学性能进行分析,研究其滞回性能和破坏模式;随后对考虑了SMA棒材直径和碟形弹簧刚度的10个模型进行了参数分析。结果表明:SC-CSL具有良好的承载能力和自复位能力,以及较小的残余变形。在拉力作用下,SMA棒材处于受拉状态且碟形弹簧保持静止;在压力作用下,SMA棒材保持静止且碟形弹簧处于受压状态,整个加载过程中双肢短剪切型耗能段发生变形并提供承载力。增大SMA棒材直径和碟形弹簧刚度均能有效提高构件的承载能力、割线刚度和自复位能力等,并能减小构件的残余变形和等效黏滞阻尼比。通过分析也能发现所推导的力学模型可较准确地计算SC-CSL的极限承载力,为该种构件的分析与设计提供理论基础。
Based on the coupled shear link, shape memory alloy (SMA) bars and disc springs, an innovative self-centering coupled shear link (SC-CSL) is developed, which can effectively improve the seismic performance and seismic resilience capacity for the concentrically braced steel frame structure. The mechanical property of the SC-CSL was analyzed by the validated finite element method, so the hysteretic performance and failure mode can be obtained. Then ten numerical models were established to investigate the influence of SMA bar diameters and disc spring stiffness. Numerical results show that the SC-CSLs have excellent bearing capacity and self-centering capacity with low residual deformation. The SMA bars mainly sustain tension with the static disc springs under tension, and the disc springs mainly sustain compression with the static SMA bars under compression, while the coupled shear link can provide the bearing force during the whole loading process. Increasing the SMA bar diameters and disc spring stiffness of SC-CSL can improve the bearing capacity, secant stiffness and self-centering capacity, and reduce the residual deformation and equivalent viscous damping ratio simultaneously. Finally, the proposed mechanical model can accurately predict the maximum loads, which can provide the theoretical basis for the design and analysis of the SC-CSL.
