摘要

摘要: 为提高大直径NiTi 形状记忆合金（SMA）棒的力学性能，设计了6组不同热处理条件下的SMA棒进行恒定增量应变循环加载，得到SMA棒的应力-应变曲线、累积耗能量、残余变形及割线刚度等力学性能指标，提出了SMA棒本构模型。结果表明：随着热处理温度的增加，SMA棒的残余应变及最大应变均增大；在相同加载位移下，热处理温度越低，SMA棒应变量越高；当热处理温度一定时，随着加热时间的增长，SMA残余变形逐渐增大。当热处理温度为400 ℃、加热时长为15 min时，SMA棒的力学性能最佳。此外，将SMA棒应用到带摩擦阻尼器的钢结构梁柱节点进行有限元分析，结果表明：附设SMA-摩擦阻尼器的钢结构梁柱节点模型的滞回曲线呈现出良好的“捏缩”效应，残余变形显著减小，表现出良好的可恢复功能。

Abstract: To improve the mechanical properties of large-diameter NiTi shape memory alloy （SMA） bars， six groups of SMA bars under different heat treatment conditions were designed for constant incremental strain cyclic loading. The stress-strain curves， cumulative energy consumption， residual deformation， secant stiffness， and other mechanical property indicators of the SMA bars were obtained， and a constitutive model of the SMA bars was proposed. The results showed that with the increase of heat treatment temperature， both the residual strain and maximum strain of the SMA bars increased. Under the same loading displacement， the lower the heat treatment temperature， the higher the strain of the SMA bars. When the heat treatment temperature was constant， with the increase of heating time， the residual deformation of SMA gradually increased. When the heat treatment temperature reached 400 °C and the heating time reached 15 minutes， the mechanical properties of the SMA bars were optimal. Furthermore， finite element analysis was conducted on a steel beam-column joint equipped with a friction damper using SMA. The results showed that the hysteretic curves of the steel beam-column joint model equipped with the SMA-friction damper exhibited a significant "pinching" effect， leading to a notable reduction in residual deformation and demonstrating excellent recoverable functionality.
