theoretical analysis on the behavior of reinforced industrial shed structures with shape memory alloys

Shape memory alloys (smas) are functional materials that feature shape memory effects and super-elasticity. these features have made smas efficient materials for reinforcement and improvement of the stability of a structure. the present study investigated the effect of 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 external post-tensioning using sma tendons is an effective way to increase the load-carrying capacity of industrial sheds. in the maximum load capacity of the frame for the steel and sma tendons increased by 36 and 60%, respectively. the performance of the sheds was improved by local post-tensioning, which can reduce the weight of the structures.
