Baker, D.J., Xie, Y.M. and Dayawansa, P.H., 1997. Numerical Predictions And Experimental Observations Of The Structural Response Of Steel Columns To High Temperatures. Fire Safety Science 5: 1165-1176. doi:10.3801/IAFSS.FSS.5-1165
ABSTRACT
The response of structural steel columns to high temperatures is investigated. Both numerical prediction and experimental testing are carried out. The material properties of the steel are obtained from a series of tensile coupon tests at various temperatures and two different strain rates. A high strain rate was used to determine instantaneous material properties, while a low strain rate allowed some creep strain to be included implicitly. These strain rate dependent material properties are incorporated in a U t e element analysis (FEA) to simulate the results of stub column buckling tests, conducted at range of temperatures up to 600°C. Good agreement has been obtained between the numerical simulations and the tests.
