【摘要】：形状记忆合金是一种具有多种特性的新兴功能材料,本文针对地震作用下空间结构的主要受力和变形特点,基于形状记忆合金独特的超弹性和形状记忆效应等,研发了形状记忆合金被动控制、主/被动混合控制系统,将其集成于空间结构模型中,并进行了相应的模拟地震振动台试验和分析。研究结果表明,对空间结构模型施加不同幅值的地震波,混合方案的控制效果明显优于优化方案和随机方案,加速度和层间位移明显减小,提高了空间结构的整体抗震性能。
[Abstract]:Shape memory alloy (SMA) is a new functional material with many characteristics. In this paper, according to the main stress and deformation characteristics of spatial structures under earthquake, based on the unique hyperelastic and shape memory effects of SMA, The shape memory alloy passive control active / passive hybrid control system is developed and integrated into the spatial structure model and the corresponding shaking table test and analysis are carried out. The results show that the control effect of the hybrid scheme is better than that of the optimization scheme and the random scheme, and the acceleration and the interstory displacement are reduced obviously, and the overall seismic performance of the spatial structure is improved by applying the seismic waves with different amplitudes to the spatial structure model.
