Abstract :
The shape memory alloys (SMAs) is a specific property some materials have to restore their original shape. This strange behavior has caused these materials to be classified as smart materials. Due to the capabilities of this material, it has been used in all industries, and in the last decade, its use has developed tremendously. In this article, while dealing with their general properties and production method, their applications especially in structural and earthquake engineering have been reviewed and investigated. For this reason, some of the works and studies done by structural engineering researchers in the recent period (from 2014 to 2024) in the field of structural engineering and with the approach of evaluating connections equipped by shape memory alloys have been mentioned. Finally, while examining the details of a Practical study in the field of steel column connection to the foundation, which was done with and without using of shape memory alloys, the advantages of using shape memory alloys in connections are summarized in the results.
