Windows and glazed doors are components of a façade that must not be subjected to any loads from the building structure. Therefore, the windows must be separated from the surrounding components by joints of appropriate sizes. On the other hand, any forces absorbed by the window must be safely diverted into the supporting construction with zero stress.
In most cases, wind forces are the main static load on the window and are therefore decisive for determining the size of the frame construction, the glass and the attachment in the structure. The load sizes can be determined under consideration of DIN 1055, Part 4.
The dead load is made up of the net weight of the frame, the glazing, the fitting parts and any sun protection equipment. The dead loads take effect vertically.
The wind forces that occur are dependent on the geographical position, the environment, the building height and the position of the windows in the building. Wind forces take effect horizontally.
Net loads are generally line loads at sill height dependent on the usage of the building. They take effect horizontally.
These are used in particular where fall protection must be guaranteed. They take effect horizontally.
These loads can be, for example, building maintenance units for cleaning the façade, anchoring loads for scaffolding etc.
Snow and ice loads
These loads can affect cleaning platforms, for example. They take effect vertically.
