Abstract

Fire is often the dominant design criterion for aluminium Structures. Present design rules neglect both the decrease in susceptibility to local buckling and the effects of creep that are intrinsic to aluminium and may therefore either under or over predict the temperature of failure depending on the load and exposure period. As part of a larger research program aimed at remedying this situation, the present paper reports the results of an experimental study on 28 aluminium SHS members with varied cross-sections, temperature(-gradient)s and heating rates loaded in bending. The experimental setup is novel itself and employs an electric heating tube or "sock" on the inside of the specimen as well as heated supports and load application point, delivering a high degree of control of temperature in time and a consistent temperature in space.
