Material properties and buckling behaviour of cold-formed thin-walled steel members under elevated temperatures due to fire
Cold-formed thin-walled steel members with a thickness of around 1 mm have been used in Japan as structural members for residential houses since the 1990s. Application of the members to houses requiring fire resistance has been limited, however, mainly because of a lack of information on the mechanical properties and buckling behavior of such a thin steel member at elevated temperatures. In this research, therefore, material tensile tests and compression column tests were conducted to clarify these characteristics, and to examine if existing column design formulae for normal temperatures could be applicable. The tests covered thicknesses from 0.5 mm to 1.6 mm and temperatures up to 600 deg C. It is reported in this paper that little difference from traditional, thicker building members was observed in yield strength and Young's modulus degradations up to 400 deg C, and existing column design formulae for normal temperature could be applied for the strength estimation.
