Test Methods for Determining the Contribution to the Fire Resistance of Structural Members - Part 9: Applied Fire Protection Systems to Steel Beams with Web Openings
Also Known As:
The DIN EN 13381-9 standard focuses on test methods and assessment procedures for determining the contribution made by fire protection systems to the fire resistance of structural steel beams with web openings. Specifically, it addresses beams that are horizontally positioned and have openings within the web, which can potentially impact the overall structural performance of the beam.
This standard applies to beams that are exposed to fire on three or four sides. It is important to note that it is not an independent standard but rather should be used in conjunction with the EN 13381-4 or EN 13381-8 standards, which outline the testing and assessment processes for fire protection materials. The European Standard EN 13381-9 relies on the multi-temperature analysis (MTA) derived from either EN 13381-4 or EN 13381-8 as the basis for determining the appropriate thickness of fire protection for beams with web openings.
To carry out the analysis, the MTA needs to be conducted separately on the web and bottom flange, resulting in an elemental multi-temperature analysis (EMTA). In the case where a beam is exposed to fire on all four sides, the bottom flange EMTA can be used as the top flange EMTA.
