Abstract
Cold-formed thin-walled steel (CFS) building systems are widely used in residential construction due to their good seismic behaviour, rapid construction efficiency and high material properties. Although significant work has been conducted on CFS members and subsystems, including studs, beams, shear walls and floors, few researches exist on the seismic performance of full-scale building systems. In order to investigate the seismic response of the CFS building system, shake table tests on a prefabricated full-scale one-story complete building were carried out. The fundamental frequency, damping ratio, displacement response and acceleration response were summarized in this paper. Then a simplified nonlinear finite element model was established with commercial software ABAQUS and validated against the test results. It was found that the developed model was suitable to accurately simulate the dynamic responses of the tested building. Hereafter, parametric studies were preformed based on the validated model to investigate the influence of key parameters on the seismic behaviour of the CFS systems, including sheathing of shear walls, diagonal brace, numbers of stories, aspect ratio as well as plan layout. Finally, based on the test data and numerical analysis results, improved seismic construction measures were proposed to provide more applicable objectives for CFS structures.
