عنوان انگلیسی Theoretical Analysis on the Behavior of Reinforced Industrial Shed Structures with Shape Memory Alloys
چکیده انگلیسی مقاله Shape memory alloys (SMAs) are functional materials that feature shape memory effects and super-elasticity. 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.
