Experimenteel onderzoek op het gebied van brand

Enkele voorbeelden van experimenteel onderzoek waaraan het laboratorium heeft deelgenomen worden hieronder toegelicht.

CSTC (since 2005)

2005-2006 - 7 tests on load-bearing walls: validation of different implementations (clay block walls vs. aggregate concrete, different thicknesses, rectified blocks vs. unrectified, masonry with traditional mortars vs glue mortars)
2010 - Test on 4 modules: implementation of solutions for joining ceilings, floors and walls in wooden frame houses
2010 - Test on 36 UHPC (ultra-high performance concrete) cylindrical specimens suspended from their upper face to an aerated concrete roofing slab
2016 - Test on 6 facade modules made of wooden frames, which openings are filled with different solid panels and insulations, and fixed in front of a supporting floor
2016 - Test on a load-bearing wall made of a wooden structure, braced by panels placed on the non-exposed fire side, and filled with a rockwool insulation

PRECOBEAM (2009)

SPF INTERIEUR (2011)

The topic of this research was the determination of the factor m.

The Basic Standards for fire prevention classify industrial buildings according to the characteristic fire load q_fi,d [MJ/m²], which is the total heat load per unit area at the ground q_fi,k [MJ/m²] corrected by a combustion factor m [dimensionless], a value between zero and one, which takes into account the total or partial combustion of materials, i.e. qfi,d = qfi,k . m.

The suggestion was to separate and identify separately the two aspects "combustion efficiency" and "participation rate", so that the combustion factor is defined by m = hc . hp.

Six goods were tested: white flour for bread, potatoes, compacted textiles, toilet paper, wood pellets, wooden boards.

ATTEL (2011)

The issue of this research was performance-Based approaches for high strength tubular columns and connections during earthquake and fire loadings.

The ATTEL project aims at developing performance-based design approaches where the capacity design of steel grades up to S690 and S700MC – widely used in seismic engineering to avoid brittle failure and ensure ductile behaviour – will be extended to high strength steel circular hollow section structures to prevent failure and collapse under both earthquake and fire loading.

LOCAL FIRES (2012)

Normally structures are designed to resist fully developed compartment fires for a specified time. In large compartments fully developed compartment fires are, however, unlikely to occur. Relatively large local fires which do not flashover the compartment may, however, develop and threaten e.g. a steel column. The purpose of the experiments is to characterize the thermal exposure levels by radiation and convection of a column surrounded by liquid pool fires by measurements with thermocouples and heat flux meter.

FIDESC4 (2012)

FIDESC4 stands for Fire Designed Structure with Class 4.

Eight tests were performed on eccentrically loaded columns: 2 laminated specimens and 6 welded specimens, with constant or variable section.

The heating was applied by electrical mats wrapped around the specimen.

Initial deformation of the specimens were measured before the tests in order to be introduced in the numerical simulations (validation of the numerical models) and to predict likely locations of local buckling where displacement transducers could be located.

LOCAFI (2013)

The LOCAFI reseach was the continuation of the “Local Fires” research.

Different specimens, consisting of tubular columns (ø 203 mm / L 4000 mm) and H-profile (HEA300 / L 4000 mm), were paced in different pools (diameters : 0,6 – 1,0 – 1,4 – 1,8 – 2,2 m) and subjected to fires feeded by differents combustibles (diesel, n-heptane, wood cribs). A total of 24 different such combinations were tested, with a common rate of heat release HRR per square meter of 500 kW/m².
