“…Considering the wall deformation with external load (load‐bearing) already showed that the position of the maximum deformation was shifting 7 . The mechanical load on a wall from an expanding test specimen during FRTs was not reported in literature so far, besides recent studies of Prieler et al 25 and Nassif et al 26 Prieler et al measured the wall deformation during FRTs when a single leaf door was tested. It was determined that the presence of the door was shifting the position of the maximum deformation of the brick wall significantly.…”

In the case of a fire event, structural components are exposed to a thermal load. To determine the fire resistivity of building components standardized fire resistance tests (FRTs) have to be carried out. Besides the heating and the deformation of building components during the FRT, also the fire response of the adjacent wall construction is important. In the past, the fire response (deformation) of masonry brick and stud walls was examined without building components placed in the wall. However, the thermal expansion of doors and other components is causing a mechanical load on the wall, which is affecting its deformation. Thus, in the present study the deformation of masonry brick walls and gypsum-sheathed stud walls with fire safety steel doors placed in the walls were determined during FRTs. Furthermore, the effect of the different door types, door size and wall thickness on the wall deformation was evaluated. Single leaf doors were approx. 1.3 m Â 2.5 m, while double leaf doors were twice the size. The maximum deformation of the masonry brick walls was between 20 and 40 mm, and was hardly affected by the door type and size. However, larger doors with a higher temperature and thermal expansion showed a slightly increasing deformation. In contrast, stud walls were significantly affected by the door, especially when small doors were used. The wall was deformed up to approx. 100 mm for small doors. Using large doors in the stud wall, the wall deformation was limited to 20 mm.

“…The relevant test results were used to assess differences in the fire behavior of hinged doors under natural fire scenarios compared to stan- dard fire testing. Nassif et al [8] conducted standard fire tests on single-leaf steel doors which were mounted on drywall or masonry walls. In this study, the direction of door opening as well as the type of wall frame were found to significantly affect the fire resistance rating.…”

The performance of fire doors is essential for the fire safety in buildings. In the present study, a series of large-scale fire tests on sliding doors is performed in the facilities of the Danish Institute of Fire and Security Technology. The test specimens comprise typical and commercially available door solutions for building applications. Similar doors of approximate dimensions 3 m × 3 m and 5 m × 3 m (width × height) are examined, while separate tests are conducted for each side of door exposed to fire. In all cases, the test specimens are mounted on appropriate wall frames of aeriated concrete as used in practice. The test results are compared in terms of transient temperature and deflection measurements. Findings reveal that the examined sliding doors exhibit satisfactory fire performance meeting the classification requirements. The overall fire performance is not affected by the width opening of door, while the fire resistance rating is significantly influenced by the side of exposure to fire. Finally, the failure characteristics are discussed, and the fire behavior of sliding doors is evaluated.

“…The proposed numerical model is compared with the corresponding experimental results in terms of temperature and deflection measurements, while sensitivity analyses are carried out to investigate the effect of the main modeling parameters. Relevant numerical studies are very limited in the literature due to the scarcity of experimental fire test results (Tabaddor and Jadhav, 2013;Joyeux, 2002;Nassif et al, 2016;Tabaddor et al, 2009;Capote et al, 2013;Boscariol et al, 2015). The numerical methodology and recommended practices for modeling the thermo-mechanical behavior of steel structures are discussed in support of the performance-based fire design standards.…”

PurposeThe purpose of this study is to contribute toward providing the main aspects of numerical modeling the fire behavior of steel structures with finite elements (FEs). The application of the method is presented for a characteristic case study comprising the series of large-scale fire door tests performed at the Danish Institute of Fire and Security Technology.Design/methodology/approachFollowing a general overview of current practices in structural fire engineering, the FE method is used to simulate the large-scale furnace tests on steel doors with thermal insulation exposed to standard fire.FindingsThe FE model is compared with the fire test results, achieving good agreement in terms of developed temperatures and deformations.Originality/valueThe numerical methodology and recommended practices for modeling the fire behavior of steel structures are presented, which can be used in support of performance-based fire design standards.
