UNE-EN 16612:2020

This European Standard gives a method of determining the design value of the bending strength of glass. It gives:

the general method of calculation, and

guidance for lateral load resistance of linearly supported glazed elements used as infill panels;

NOTE Examples of lateral loads are wind loads and snow loads and self weight of sloping glass and climatic loads on insulating glass units.

This standard gives recommended values for the following factors for glass as a material:

material partial factors, ³M;A and ³M;v ;

factors for the load duration, kmod ;

partial factor for actions, ³G , ³Q , and È ;

factor for stressed edges, ke.

Most glass in buildings is used as infill panels. Infill panels are in a class of consequence lower than those covered in EN 1990, so proposed values for the partial load factors, ³Q and ³G, are given for infill panels.

The action of climatic loads on insulating glass units is not covered by Eurocodes, so this document also gives proposed values of partial factors, È0, È1 and È2, for this action.

This European Standard does not determine suitability for purpose. Resistance to lateral loads is only one part of the design process, which may also need to take into account, for example:

" in-plane loading, buckling, lateral torsional buckling, and shear forces

" environmental factors (e.g. sound insulation, thermal properties),

" safety characteristics which cannot be calculated (e.g. fire performance, breakage characteristics in relation to human safety, security, containment).

This European Standard does not apply to channel shaped glass.
