==== Civil structures ====
SMAs find a variety of applications in civil structures such as bridges and buildings. In the form of rebars or plates, they can be used for flexural, shear and seismic strengthening of concrete and steel structures. Another application is Intelligent Reinforced Concrete (IRC), which incorporates SMA wires embedded within the concrete. These wires can sense cracks and contract to heal micro-sized cracks. Also the active tuning of structural natural frequency using SMA wires to dampen vibrations is possible, as well as the usage of SMA fibers in concrete.<ref name=Song>{{Cite journal | doi = 10.1016/j.engstruct.2005.12.010| title = Applications of shape memory alloys in civil structures| journal = Engineering Structures| volume = 28| issue = 9| pages = 1266| year = 2006| last1 = Song | first1 = G.| last2 = Ma | first2 = N.| last3 = Li | first3 = H. -N. | bibcode = 2006EngSt..28.1266S}}</ref>
