Triangular windows used in the presented project consist of two separate aluminium frames. First, a light-weight base-frame is mounted on the walls. Afterwards, the triangular window itself can slide into this base-frame. This approach minimises the assembly time. The aluminium profiles used are designed and manufactured especially for this project. The aluminium window frames are completely modelled in SCIA Engineer, which gives us the possibility to check all local stresses. It was also possible to check the local stresses in the connection between the insulator and inner and outer aluminium frames. These stresses must be kept low to avoid breaking of the insulator. Moreover, it was possible to determine the exact displacement of glass supports. This displacement is important due to the triangular shape of the glass. The glass support is placed in the middle of the opposite side. If the deflections are too large, the glass would move too much in the vertical direction, which could result in an insufficient airtightness. By placing the glass higher in the frame based on the deflections calculated in SCIA Engineer, this problem was eliminated. SCIA Engineer was also used to check the stresses and deformations in the curved glass panels. Due to the curved shape of the glass it was not possible to use standard 2D-software.
