Journal of Coastal Research, Special Issue No. 94, pp. 213–217. Coconut Creek (Florida), ISSN 0749-0208.The coastal area of South China is a frequent seismic activity area. To improve the seismic performance of architectural structures in the coastal areas of South China, this paper proposed a Niche Bat Algorithm (NBA) Wavelet Neural Network (WNN) constitutive model of Shape Memory Alloy (SMA), and compared it with WNN model and BA-optimized WNN (BA-WNN). The paper applied SMA to the seismic control of truss structure, and the obtained SMA control system can more effectively reduce the interlayer displacement of the structure and alleviate the seismic response of the structure, it provided a new method for seismic resistance of coastal structures.
