Structural Performance of Light Gauge Steel Compression Members at Elevated Temperatures
Mahendran, Mahen & Ranawaka, Thanuja N. (2007) Structural Performance of Light Gauge Steel Compression Members at Elevated Temperatures. In Richard Liew, J.Y. & Choo, Y.S. (Eds.) 5th International Conference on Advances in Steel Structures, 5-7 Dec 2007, Singapore.
Despite the importance of fire safety design of building structures, the structural behaviour of light gauge cold-formed steel members under fire conditions is not well understood. The light gauge steel members are susceptible to various buckling modes including distortional buckling. The distortional buckling effects associated with thin and high strength steel members are significant and the effects of fire conditions on the distortional buckling behaviour are not known. Therefore a research project was undertaken to investigate the distortional buckling behaviour of light gauge cold-formed steel members under axial compression. It included tensile coupon tests to determine the mechanical properties and detailed laboratory experiments and numerical analyses of channel members subject to axial compression at elevated temperatures up to 800 degrees Celsius. The results were compared with the current design rules and appropriate modifications were proposed. This paper presents a summary of the results from this investigation on the distortional buckling behaviour of cold-formed steel columns.

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.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
