Abstract [en]
Timber and glass are materials with aesthetically pleasing properties. If the materials can be combined appropriately, drawbacks can be overcome and the beneficial mechanical properties utilised and timber/glass elements can be a natural part of the load-carrying structure of buildings. Since glass is a brittle material, an important task for the timber is to provide redundancy – a glass failure should not lead to a catastrophic failure of the entire structural element.
This paper presents results from ongoing research related to load-bearing components made of timber and glass. Results from tests on small timber/glass bond-line specimens, recently submitted for publication, are briefly presented. The core of the paper is, however, a study of fourpoint bending tests on twelve timber/glass I-beams with acrylate adhesive. These I-beams had a nominal height of 240 mm and were designed with a web of 10 mm float glass and flanges of LVL (laminated veneer lumber), bonded together with an acrylate adhesive.
The mean values of the beams imply that the ultimate load capacity is 240 % of the load when the fi rst crack in the glass appeared. Thus, the timber well fulfils the redundancy task of avoiding a catastrophic failure of the structural element.
