Seismic Control of Steel Structures with Shape Memory Alloys

Shape Memory Alloys (SMA's) are able to reach very large recoverable strains. They have found their means into many inventive applications including seismic structural control. Due to their recentering capability as well as damping capacity, SMA materials are favorable for use in earthquake applications. The main idea of this research is the simultaneous use of SMA elements in different phases and steel elements is structural systems, in order to utilize each favorable characteristics. Damping capacity of Martensite phase of the SMA will leave residual strains in structure which is in contrast with the recentering characteristic of Austenite phase of the SMA. Therefore an attentive arrangement will be required in order to get the best structural performance. In this article an initiative was taken for arranging different states of SMA materials in structures as bracing elements in order to reach the best feasible performance.
