This paper presents the test and evaluation results on the shear strength and stiffness of a light steel stud wall from a lightweight foamed mortar (lightweight hybrid wall). The use of a lightweight foamed mortar was aimed at improving structural performance, thermal performance, and finish. Studiesshowed that it did not affect thermal performance, but it contributed to structural performance and finish when the unit weight was more than 0.8 (Editor's note: Please indicate the unit of measurement.). In this study, 14 specimens-whose parameters included the specific gravity of the lightweight foamed mortar (0.6, 0.8, 1.0, 1.2), the spacing of the stud (450 mm, 600 mm, or 900 mm), finishing materials (such as lightweight foamed mortar, OSB, and gypsum board), and bracing-were manufactured. Three typical, steel house-framing specimens were added to compare the test results with the 14 specimens. The results of in-plane shear tests show that the use of lightweight foamed mortar (1.15~5.38 times stronger, 1.45~13.7 times stiffer) results in ultimate strength and initial stiffness. In addition, it was possible to widen the stud spacing to up to 900 mm without decreasing shear strength. It was very important to prevent the lightweight foamed mortar from shrinking and to secure the adhesion between the steel stud and the lightweight foamed mortar to improve structural performance.
