摘要
形状记忆合金(SMA)是一种性能良好的智能材料,它与混凝土结构的结合克服了传统混凝土的一些缺陷,并在抗震设计方面体现出强大的优势。通过介绍智能材料结构的发展概况,详细阐述了形状记忆合金的工作原理、特性,根据使用方式的不同划分的内置与外置SMA智能混凝土,以及不同研究者的成果,总结了各自的特点及不足,并探讨了未来的发展方向及研究重点。
The Shape Memory Alloy has a good performance of smart materials to overcome some shortcomings of the traditional concrete. Its combination with concrete structures reflects a strong advantage in seismic design. This article describes the overview of the development of smart materials and structures, and details of the working principle of Shape Memory Alloys, characteristics. According to the use of different ways, it can be divided into internal and external SMA smart concrete. This paper summarizes the results of different researchers, their own characteristics and deficiencies. Finally it explores the future direction of development and research priorities.
