Analytical methods for determining fire resistance of steel members

Abstract

Traditionally, fire resistance has been evaluated by subjecting a structural member to a standard test for a specified duration [1]. All members performing acceptably are rated and listed for the duration period of the test (e.g., 1 h, 2 h). Assemblies not listed are assumed to be unable to meet the test criteria and thus have no rating, unless proven otherwise. Providing proof of acceptable performance can be accomplished in one of three manners.
