These features have made SMAs more efficient materials for reinforcement and improvement of the stability of a structure. The present study aims to investigate the effect of the local post-tensioning with SMAs to improve the load-carrying capacity of tapered steel industrial sheds. For this purpose, ABAQUS software was used to predict the flexural strength and load-bearing capacity of the alloys. The effects of the diameter and the post-tension force applied to the SMA tendons were investigated. The results showed that the external post-tensioning using SMA tendons is an effective way to increase the load-carrying capacity of industrial sheds. The steel and SMA tendons caused a 36% and 60% increase, respectively in the maximum load capacity of the frame. The performance of the sheds was improved by local post-tensioning, which can reduce the weight of the structures.
