Determination of the strength of infill supports - Test method and requirements

This European Standard specifies test methods for the determination of bearing capacity (ultimate limit state and serviceability limit state) of infill support which cannot be calculated in accordance with current codes or conventional calculations based upon the strength of the materials.
Mechanical performances of the infill support are already assessed while testing the glazed product or infill in regards to safety in use. Additional information with respect to mechanical performance of the infill support and direct applications can be determined with this standard.

Bestimmung der Festigkeit von Auflagern für Ausfachungen - Prüfverfahren und Anforderungen

Diese Europäische Norm legt Prüfverfahren zur Bestimmung der Tragfähigkeit (Grenzzustand der Tragfä-higkeit und Grenzzustand der Gebrauchstauglichkeit) von Auflagern für Ausfachungen fest, die nicht nach geltenden Codes oder herkömmlichen Berechnungen, die auf der Festigkeit der Werkstoffe basieren, berechnet werden können.
Die mechanischen Leistungen des Auflagers für Ausfachungen werden bereits während der Prüfung des verglasten Produkts oder der Ausfachung bezüglich der Gebrauchssicherheit bewertet. Zusätzliche Angaben zur mechanischen Leistung des Auflagers für Ausfachungen und zu den direkten Anwendungsbereichen können nach dieser Norm bestimmt werden.

Détermination de la résistance des supports de vitrage (panneaux de remplissage) - Méthode d'essai et exigences

La présente Norme européenne spécifie des méthodes d'essai pour la détermination de la capacité
portante (état limite ultime et état limite de service) d'un support de remplissage, qui ne peut pas être
calculée selon les codes actuels ou les calculs conventionnels reposant sur la résistance du matériau.
Les performances mécaniques du support de remplissage sont déjà évaluées lors de l'essai de la paroi
vitrée ou du panneau de remplissage eu égard à la sécurité d'utilisation. Des informations
supplémentaires relatives aux performances mécaniques du support de remplissage et à ses applications
directes peuvent être déterminées sur la base de la présente norme.

Ugotavljanje trdnosti podpore polnil - Preskusne metode in zahteve

Ta evropski standard določa preskusno metodo za ugotavljanje obremenitvene zmogljivosti (končno mejno stanje in uporabnostno mejno stanje) podpore polnil, ki je ni mogoče izračunati v skladu z veljavnim kodeksom ali konvencionalnim izračunom na podlagi trdnosti materialov.
Mehanska zmogljivost podpore polnil je ocenjena že med preskušanjem zastekljenih izdelkov ali polnil v povezavi z varnostjo uporabe. S tem standardom je mogoče določiti dodatne informacije glede mehanske zmogljivosti podpore polnil in neposredne uporabe.

EN 17146:2018 (E) 3 European foreword This document (EN 17146:2018) has been prepared by Technical Committee CEN/TC 33 “Doors, windows, shutters, building hardware and curtain walling”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2019, and conflicting national standards shall be withdrawn at the latest by June 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This standard has been developed by CEN/TC 33/WG 6 Curtain walling for the purpose of curtain walling systems, but can be used also for similar constructions and fenestration products. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 17146:2018 (E) 4 1 Scope This document specifies test methods for the determination of the bearing capacity (ultimate limit state and serviceability limit state) of infill support which cannot be calculated in accordance with current codes or conventional calculations based upon the strength of the materials or to compare the calculation when necessary. Three different types of infill (glass) supports are dealt in this standard: — The cantilever infill (glass) supports, see Figure 1 (a); — The cruciform infill (glass) supports only fixed to the mullion, see Figure 1 (b); — Corner infill (glass) supports only fixed to the mullion, see Figure 1 (c). The test method is intended for the assessment of cantilever infill (glass) supports that have not been tested according to EN 16758 (see Figure 9). The results of the test method can only be interpreted when incorporated with the results from a test in accordance with EN 16758. It is essential that cruciform and corner infill (glass) supports only fixed to the mullion are tested in accordance with this standard. The infill (glass) supports connected to the mullion and the transom together are considered as a part of sheared connection and are covered by EN 16758. Where the mechanical performances of the infill (glass) support is already assessed in accordance with the provisions described in EN 13830, additional information with respect to mechanical performance of the infill (glass) support and direct applications can be determined with this standard. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

EN 17146:2018 (E) 7 5 Method of evaluation 5.1 General Infill (glass) supports are subjected to permanent loads. These accessories shall transfer the loads in such way that the serviceability of the work in which they are applied is preserved. 5.2 Samples The samples shall be representative of the design with which the infill (glass) support transfers the permanent load to the frame profile. The supports of the samples shall restrain vertical and rotational movements of the frame profile. Principles of typical test configurations are shown in Figure 1 for the cantilever infill support, the corner infill support, the cruciform infill support, but different configurations may be used depending on product’s technology. The infill (glass) support frame is to be blocked against rotation in order to minimize the influence of the frame on the glass support.

Figure 1 —Schematic examples of application of vertical load (Fv) Vertical load (Fv) should be applied to the glass support in the way the permanent vertical load is applied in practice. In case the infill is an insulating glass unit, to establish the serviceability limit state (Annex A), in absence of evidence from the glass manufacturer or the system designer, it is advised to limit the deformation of the glass support in order to obtain a maximum displacement of 1 mm between two consecutive glass panes and the distance “g” should not be less than 25 mm. The samples are built according to Figure 1 for which the following apply:
For the cantilever infill support — p: maximum thickness of the infill panel, also measurement reference points for the infill support deflection; — the length of the frame profile “r” should not be less than the length of the glass support “L” + 20mm. — the transducers DT1, DT2 are normally placed at the orthogonal projection of the end of the width of setting blocks. SIST EN 17146:2019



EN 17146:2018 (E) 9
For the corner/cruciform infill support — “i”, the maximum distance between the longitudinal axis of the mullion and the infill setting block; — “k”, the maximum length of the setting block; — the total height of the mullion of the sample is not less than height of the cruciform ht + 2 x 25mm; — the transducers DT2, DT4 are normally placed at the projected ends of the setting blocks except if contact between the extremity of the horizontal flange of the glass support and the infill is can be expected during the test. In the case, the transducers DT2, DT4 shall be placed at extremity of the flange(s) l, ll, and lr; — the transducer DT1, DT3 are normally placed at the projected ends of the nearest of the mullion setting blocks extremity. 5.3 Loadings 5.3.1 General 5.3.1.1 Preload
