| 摘 要： | 形状记忆合金是一种在结构振动控制领域具有广阔应用前景的智能材料,利用它的形状记忆效应、超弹性效应和高阻尼特性等特点,可实现结构的振动控制.但土木工程结构体型大、结构材料粗糙(如混凝土)和结构荷载巨大,而SMA材料价格昂贵,因此在土木工程中的应用显然存在一些问题.本文指出了应用SMA进行土木结构振动控制时存在的难点问题,以期在研究和应用中引起重视,扬长避短,达到较好的振动控制效果. |

| Abstract: | Shape Memory Alloy(SMA) is one of class of smart material which has been shown of broad application prospects in civil engineering structural vibration control.Based on the special features of shape memory alloy in shape memory effect,super-elastic property and high damping capacity,etc,we can achieve to control vibration in structure.Because civil engineering structure shape is too big and it's load is very heavy and it's material is rough(such as concrete),moreover SMA material is expensive,there are some... |
