Abstract

A series of local buckling tests of light gauge cold-formed steel columns was conducted at ambient and elevated temperatures up to 700oC to fully understand their local buckling behaviour under fire conditions. Current design standards do not provide clear guidelines for cold-formed steel structural members under fire conditions. Although Eurocode 3 Part 1.2 provides some guidelines for local buckling, other imposed limitations may lead to uneconomical designs. Some designers use the design guidelines developed for ambient temperature conditions to calculate the local buckling capacities at elevated temperatures by simply using the reduced mechanical properties. This paper presents the details of local buckling tests and reviews the accuracy of different design methods for estimating the local buckling capacities of cold-formed steel compression members at elevated temperatures.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® 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 the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
