Metode ispitivanja za određivanje doprinosa otpornosti konstrukcijskih elemenata na požar — Deo 6: Zaštita primenjena na šuplje čelične stubove ispunjene betonom

Наслов на енглеском језику

Test methods for determining the contribution to the fire resistance of structural members - Part 6: Applied protection to concrete filled hollow steel columns

Апстракт на српском језику

Ovim standardom se utvrđuje metoda ispitivanja za određivanje doprinosa sistema za zaštitu od požara otpornosti na požar čeličnih stubova ispunjenih betonom. Beton može da bude lak, normalan ili težak, i svih klasa čvrstoće datih u SRPS EN 1994-1-2. Metoda je primenjiva na sve sisteme zaštite od požara koji se koriste za zaštitu šupljih stubova ispunjenih betonom i obuhvata sisteme za zaštitu od požara prskanjem, reaktivne premaze, sisteme sa zaštitnim oblogama i višeslojne ili kompozitne materijale za zaštitu od požara.

This European Standard specifies a test method for determining the contribution of fire protection systems to the fire resistance of structural concrete filled hollow steel columns. The concrete can be lightweight, normal-weight or heavyweight concrete, and of all the strength classes provided for in EN 1994-1-2. The use of a dry sand is considered to be an alternative, conservative approach to the use of wet concrete. A specification for dry sand is given in 5.6.3. The method is applicable to all fire protection systems used for the protection of concrete filled hollow columns and includes sprayed fire protection, reactive coatings, cladding protection systems and multi-layer or composite fire protection materials. If there is no hollow section data from EN 13381-4 or EN 13381-8, this European Standard cannot be used. For passive systems, this data can be derived using the Formula in Annex A of EN 13381-4:2002. Testing to this European Standard is not required if the fire protection thicknesses for hollow sections derived from EN 13381-4 or EN 13381-8 are to be used for concrete filled hollow sections. The evaluation is designed to cover a range of thicknesses of the applied fire protection material, a range of steel sections, characterized by their diameters and wall thicknesses, a range of design temperatures and a range of valid fire protection classification periods. The test method is applicable to fire protection systems which are intimately in contact with the structural column, or which include an airspace between the structural column and the protection system. This European Standard specifies the fire tests which are carried out to determine the ability of the fire protection system to provide fire protection to composite columns. The tests produce data on the average steel temperatures of the composite column, when exposed to the time/temperature curve according to the procedures defined herein. This European Standard also provides the assessment procedure, which prescribes how the analysis of the test data should be made and gives guidance on the procedures by which interpolation is undertaken. In special circumstances, where specified in national building regulations, there can be a need to subject reactive protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in EN 13381-8. This exposure, applicable to reactive fire protection materials, is used only in special circumstances (which are specified in the national building regulations of a member state of the European Union) and is therefore not intended to be mandatory for all fire protection materials applied to concrete filled hollow steel columns. This European Standard ignores any contribution from the concrete to the structural capability of the hollow column and therefore only deals with thermal performance. The justification for using this approach is given in Annex B. The fire test methodology makes provision for the collection and presentation of data which can be used as direct input to the calculation of fire resistance of concrete/steel composite members in accordance with the procedures given in EN 1994-1-2. The limits of applicability of the results of the assessment arising from the fire test are defined together with permitted direct application of the results to different steel/concrete composite columns, steel types and thicknesses, concrete densities, strengths, thicknesses and production techniques over the range of thicknesses of the applied fire protection system tested. This European Standard details the fire test procedures, which should be carried out to provide data on the thermal characteristics of the fire protection system, when exposed to the European Standard temperature/time curve specified in EN 1363-1. The assessment procedure is used to establish: a) on the basis of temperature data derived from testing concrete (...)
