“…The use of cold-formed steel (CFS) elements in wall panel systems has been gradually increasing in recent years both in the field of structural systems and as non-structural architectural components. This is due to their high strength-to-weight ratio, cost-effectiveness, prefabrication and fast assembling on-site, environmental protection and good seismic performance [1][2][3]. The connections between the floor structures and the wall panels remain questionable due to the high level of fabrication of the panels.…”

This paper presents an experimental and numerical investigation of the tensile and compressive behaviour of a novel U-connector in the cold-formed steel (CFS) truss-to-column connection. Tensile tests were performed on 12 specimens representing the tension chords of the trusses in the connection. The results were used to validate a finite element model. The validated model was then subjected to both compressive and tensile loads, which revealed low stiffness in both the compressive and tensile components of the proposed connection. An optimisation of the geometry by using one long nut instead of two nuts was carried out to improve the behaviour and stiffness of the connection. The optimised results were compared with both experimental and numerical data, and conclusions were drawn regarding the effectiveness of the components in the proposed connection. The use of long-nut optimisation in the tension and compression components of the proposed connection shows a significant increase in load-bearing capacity, which makes it very promising for future applications in CFS truss-to-column connections. However, further validation through experimental testing is required to confirm the effectiveness and reliability of the connection in full-scale structures.

“…For previous studies about CFS systems, Sani et al provided a review on roof trusses constructed using CFS [ 15 ], and Sharafi et al focused on the research and advancements made in the lateral resistance of lightweight steel frames [ 16 ]. In addition, Di Lorenzo and De Martino provided an outline of the CFS non-structural architectural and structural systems’ existing codification and ongoing research [ 17 ]. Other authors like Amsyar et al gathered and reviewed prior studies on composite joints for CFS structures, focusing on three distinctive topics: composite beam-to-column and beam-to-slab joints, and beam-to-column joints [ 18 ].…”

This paper aims to perform the experimental test and numerical FE analysis of the cold-formed steel frame structure to provide new proposals to improve the strength, rotation capacity, and seismic energy dissipation in these structures. A 3D full-scale three-story CFS frame structure is experimentally investigated under four sets of input data for 100% and 50% scales of Northridge and Kocaeli earthquake acceleration records using the shaking table test. In each test, the frame acceleration and displacement are observed. A FE model is employed to assert the validity of the experimental test. The results indicated that the maximum story drift ratio of the frame ranges from 1.14% to 3.70%. It is observed that the average similarity ratio of the maximum displacement results between FE analysis and shaking table test is 92%. It is shown that the translational stiffness for the system decrease as the earthquake acceleration records decrease. It is also shown that using the image processing technique in the shaking table test can offer much more acceptable and economical solutions in determining the displacement parameters.
