“…Truss construction has always been associated with the high end of carpentry; up to the middle of the 19th century, trusses were used predominantly in prestigious public buildings such as temples, churches, or bridges. While there is only a small body of evidence for trussed roofs of antiquity [9], there are abundant examples of long-span roof systems from the Middle Ages through the Renaissance [10] and a myriad of truss forms developed [11]. It is only during the last two centuries, that trusses became shaped by engineering analysis and design [12,13].…”

Timber architecture, taking advantage of modern production techniques, is increasingly moving towards free forms; however, traditional joining techniques are not yet adapted to echo the new expression at the level of the details. This paper reports on adhesively bonded joints as a way to help architects fully unleash their creative potential. For this purpose, experimental and numerical investigations on full-scale adhesively bonded timber trusses were performed, in which adhesive bonds were compared to traditional doweled connections. The adhesively bonded trusses achieved significantly higher failure load and stiffness. Tests on small clear specimens were conducted to determine input parameters for finite element analyses. The sole timber connection was characterised, giving valuable insights into the mechanical behaviour of this truss component. At this end, the influence of the embedded length of the applied sleet plates was experimentally determined, delivering data to benchmark the subsequent dimensioning method. The trusses were then modeled and excellent agreement was found between numerical and experimental results. Finally, a dimensioning method, based on a realistic multi-axial failure criterion coupled with size effects was implemented and yielded very good agreement when with experimental results. The reported investigation demonstrates the high potential of adhesive bonding in timber structures.
