Experimental, numerical and analytical studies on full-scale cold-formed steel center-sheathed shear walls subjected to combined loading
Abstract Conventional cold-formed steel wall systems suffer from low lateral loading-carrying capacities and stiffnesses, which represent the main barrier to their use in multi-story buildings. To address it, a cold-formed steel center-sheathed shear wall (CFSCSSW) system with higher lateral load-carrying capacity and better lateral structural performance is proposed. This paper presents experimental, numerical, and analytical studies on the behavior of the proposed CFSCSSW subjected to combined vertical and horizontal loads. Firstly, a full-scale test was conducted, with the test setup, loading procedures and measuring instrument reported in detail. The obtained test results, including the load-carrying capacity, failure mode and strains, were fully analyzed. Then, finite element modeling was conducted to simulate the experimental observations, and parametric studies were carried out to investigate the influences of different geometric and loading parameters on the behavior of CFSCSSWs. Finally, a three-strip model with a variable position on end studs (TSM-VPC) was proposed for CFSCSSWs and shown to accurately simulate the direction of the tensile field within the sheathing and also resulted in high accuracy in calculating the load-carrying capacities, followed by a design example.
Highlights An innovative cold-formed steel center-sheathed shear wall (CFSCSSW) system is proposed. A full-scale test on CFSCSSW under combined loading is conducted, with test results fully analysed. The influences of key geometric and loading parameters are investigated through parametric studies. A three-strip model is proposed for calculating the load-carrying capacity of CFSCSSW.
