Thermal design reference for steel structures

[pwht1]

Hey,

Does anyone have any decent texts, papers or guidelines for designing HOTTTTT steel beams? I'm talking 300-500 celsius and changes in temperature will be about the same magnitude.

Thanks

I once ported some steel at temperature stress-strain diagrams of one ENSIDESA (Empresa Nacional Siderúrgica) Handbook to Mathcad 2000; I think to remember it was based on european standards.

This should be enough for structural design, since valid till 600ºC; however I would be wary of additive plastic deformation on cycling loading without further examination of the question.

The Australian Steel Code (AS4100-1998) has got some information regarding the design of bare steel subject to elevated temperatures. It gives equation for the variation of yield stress and Young's modulus with temperature.

fy(T)=(905-T)/690*fy...for 215ºC<T<905ºC
E(T)=E*(1+T/(2000*ln(T/1100)))...for T<615ºC

Thanks guys, but I was looking for a more comprehensive guide if one exists. Something that would cover everything from weld degradation, connection design, out of plane deflection/warping for beams due to thermal expansion etc.
