Experimental investigation of lightweight residential floors supported by cold-formed steel C-shape joists

Presented in this paper are the experimental results of a recent study carried out at the University of Waterloo on vibration characteristics of cold-formed steel-supported lightweight residential floor systems. Laboratory tests were conducted for floors with different spans and assemblies to identify the critical parameters that contribute to the control of floor vibration. Both static and dynamic tests were carried out on the floor systems. On-site tests were also conducted in this study to substantiate the results obtained in the laboratory tests and evaluate the actual vibration performance of cold-formed steel-supported lightweight residential floor systems.
