Design of Cold-formed Steel Wall Frames Lined with Plasterboard on One Side under Axial Compression
Cold-formed steel wall frame systems are commonly made of lipped or unlipped (plain) C-section studs with Gypsum plasterboard lining and are used in the construction of both the load bearing and non-load bearing walls in residential, industrial and commercial buildings. However, the design of these wall frames does not utilise the strengthening effects of the plasterboard lining in carrying axial loads. An experimental study has shown that the strength of the studs in compression was increased significantly when they were lined with plasterboard on one or both sides. In order to fully understand the behaviour of one side lined steel wall frames, a detailed parametric study was undertaken using finite element analyses. A finite element model of one side lined wall frame was developed and validated using experimental results. This paper presents the details of the finite element modelling of one side lined steel wall frames and the results. A design method based on appropriate effective length factors was developed within the provisions of Australian/New Zealand standard for cold-formed steel structures to predict the ultimate loads and failure modes of one side lined steel wall frames.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
