“…Furthermore, a growing trend is represented by the innovative application to timber joints for constructions . [181][182][183] As an example, reference [181] and Figure 14, illustrate how a standard pull-pull test configuration can be used for the mechanical analysis and characterization of the CZM input parameters.…”

In the framework of the Cost Action CERTBOND (Reliable roadmap for certification of bonded primary structures), a wide group of researchers from 27 European Countries have had the opportunity to work on the topic of certification of bonded joints for primary structural applications from different engineering sectors such as the aerospace, automotive, civil engineering, wind energy and marine sectors. Since virtual testing and optimization are basic tools in the certification process, one of the key objectives of CERTBOND is to critically review some of the available models and failure theories for adhesive joints. The present paper summarizes the outcome of this task. Nine different models/theories are described in detail. Specifically, reviewed are the Classical Analytical Methods, the Process Zone Methods, Linear Elastic Fracture Mechanics (LEFM), the Virtual Crack Closure Technique (VCCT), the Stress Singularity Approach, Finite Fracture Mechanics (FFM), the Cohesive Zone Method (CZM), the Progressive Damage Modeling method and the Probabilistic methods. Also, at the end of the paper, the modeling of temperature effects on adhesive joints have been addressed. For each model/theory, information on the methodology, the required input, the main results, the advantages and disadvantages and the applications are given.

“…While in practice a single GiR connection is seldom used, previous research mostly focused on single rod configurations to isolate the effects of these parameters on the joint performance. In examining these parameters, previous studies focused on solid structural timber [11,12], Glue-laminated Timber (Glulam) [13,14], Laminated Veneer Lumber (LVL) [15], and more recently CLT [16,17].…”

“…Only a few studies are available on the performance of GiR connections in CLT. Azinovic et al [16,17] reported on different failure modes such as the edge lamination tear out, complete tear out of CLT layer, failure along non-glued timber edges and failure of timber next to adhesive, all of which deviate from the regular failure modes seen in other wood products and recommended further studies. Research gaps exist regarding the performance of single and multiple rods GiR in CLT such as the impact of rod edge spacing, shifting of anchorage length to inner members, load-to-grain angle and spacing between multiple rods.…”

“…The behaviour of GiR in timber inserted at different grain angles differs. The rod-to-grain angle is the angle between the grain direction of timber and the longitudinal axis of the rod [17]. Because timber is generally strongest in the longitudinal axis, one would assume GiR joints positioned parallel to this axis would have higher strength.…”

“…Azinovic et al [17] further conducted parametric finite element studies of GiR in CLT for the rod-to-grain angles 0°, 15°, 30°, 45°, 60°, 75° and 90° to examine the effects of the rod diameter, glued-in length and the rod-to grain angle on the load-carrying capacity and stiffness of the GiR connection. Generally, a good agreement was found between the experimental data and the finite element analyses.…”

Performance of glued-in-rod connections in cross-laminated timber

The widespread availability of Cross-laminated timber (CLT) provides opportunities to extend the use of wood beyond traditional low-rise residential construction. Glued-in rods (GiR) are an interesting technical solution for numerous structural applications in timber engineering. Although GiR connections have the potential to be used in combination with CLT, research on this application is scarce. In this thesis, an experimental investigation on the performance of GiR in CLT is presented. Two different 5-ply CLT panel thicknesses (139 and 175 mm), two steel rod diameters (d = 12.7 and 19.1 mm) and five different anchorage lengths (la = 6d, 10d, 12d, 14d and 18d) were considered in single and multiple rod connections. A total of 260 specimens were fabricated and subsequently tested under uni-axial quasi-static monotonic tension. The results were assessed in terms of load-carrying capacity, stiffness and failure modes and demonstrated that GiR in CLT offer an alternative high capacity timber connection.

Aufgrund des wachsenden Umweltbewusstseins in der Baubranche in Verbindung mit der zunehmenden Urba nisierung wird der nachwachsende Werkstoff Holz dank seines geringen ökologischen Fußabdrucks immer stärker in den Fokus gerückt [1]. Holzwerkstoffe, insbesondere Brettsperrholzplatten (BSP) und Brettschichtholz (BSH), bieten Architekten und Ingenieuren die Freiheit für kon struktive Anwendungen im Hochhausbau. BSP wird v. a. als großformatiges Wand, Boden und Dachelement in ein und mehrstöckigen Gebäuden, Hal len und Brücken eingesetzt. Obwohl das Produkt erst seit ca. 30 Jahren auf dem Markt ist, hat es den Holzbausek tor in vielerlei Hinsicht nachhaltig verändert, z. B. weil es Architekten erlaubt, in Flächen und Volumen statt in Li nien zu denken, indem es eine extrem schnelle, trockene, saubere und hochpräzise Konstruktion ermöglicht oder durch die Bereitstellung aller handwerklichen Voraus setzungen für eine einfache und schnelle Montage und Installation von zusätzlichen Schichten (z. B. Dämmung) und Haustechnik im Allgemeinen [2]. Um diesen Anfor derungen gerecht zu werden, bedarf es allerdings auch entsprechender hochleistungsfähiger Verbindungen. Zu diesen zählen die in diesem Beitrag thematisierten einge klebten Stahlgewindestäbe.
