عنوان مقاله [English]
One of the new construction systems is the cold-formed light steel framing system (LSF). In this research, it has been tried to take a step towards the application and localization of this system. Therefore, in this article, the effect of the size of the mortar used in the installation of bricks in brick shear walls in cold-formed steel frame has been investigated. 4 brick shear walls in cold-formed light steel frame in 2 types are completely identical but with a change in thickness in the mortar behind the bricks have been fabricated and tested. To reduce possible errors during fabrication and testing of any kind, two specimens have been constructed exactly the same and the specimens are subjected to the ASTM loading protocol and the ultimate strength and coefficient of behavior of each specimen has been calculated by Yang and Powell methods. The results show that the change in mortar thickness did not have much effect on the coefficient of behavior of the specimens. Mortar thickness has the greatest effect on the strength of specimens so that the specimen with a mortar thickness of 50 mm has a significant resistance compared to the specimen with a mortar thickness of 25 mm. Also, with a Rial estimate , it was found that the cost of building a wall with a mortar thickness of 50 mm is slightly lower than the cost of building a wall with a mortar thickness of 25 mm.
