For cases where the interaction with a single wall is sufficient, simpler fitting formulae are proposed, based on earlier results using the bispherical coordinates method.
The comparison of fitting results with test results and code results indicates that the fitting formulae are highly accurate and can predict the capacity and critical temperature of the axially compressed stainless steel columns in fire.
Comparisons of fitting results with test results and code results indicate that the fitting formulae have a high level of accuracy and can predict the ultimate bearing capacity and critical temperature of the rectangular hollow section stainless steel beams in a fire.
The reserve gains recommended by the four selected fitting formulae were allowed for [ 19].
Standard fitting formulae such as NAL-NL1 and more recently NAL-NL2 are the preferred formulae in NHS audiology departments (British Society of Audiology and British Academy of Audiology Guidance 2007).
