Summary
A computer aided numerical model for the simulation of the in-plane bending strength of CLT beams is presented. The model uses the Monte-Carlo-Method to generate mechanical characteristics of board lamellae and is suitable for the investigation of statistical effects such as homogenisation and size effects. Six different types of CLT beams, varying in size and in layup, were tested to validate the model and except for beams with only one lamella in direction of the beam height good agreement was found between the experimental results and the model’s simulations.

Summary
Cross laminated timber (CLT) members are especially suited for in-plane loads due to their high shear strength and stiffness. However, available connection techniques show limited load-carrying capacities and stiffness values in comparison to the shear capacity of CLT. To use the potential of CLT under in-plane loading, new connection techniques, so called contact joints, with increased stiffness and load-carrying capacities were developed. 10 different types of these contact joints, varying geometry and connector material, were studied. The developed contact joints can substitute traditional connection techniques.

Summary
This state-of-the-art report has been prepared within COST Action FP1402 Basis of structural timber design from research to standards, Working Group 3 Connections. The Action was established to create an expert network that is able to develop and establish the specific information needed for standardization committee decisions. Its main objective is to overcome the gap between broadly available scientific results and the specific information needed by standardization committees. This necessitates an expert network that links practice with research, i.e. technological developments with scientific background. COST presents the ideal basis to foster this type of joint effort. Chapter 8 Connections presents an integral part of Eurocode 5 and is in need of revision. This state-of-the-art report shall provide code writers with background information necessary for the development of the so-called Second Generation of the Eurocodes, now aimed to be produced in 2022.

Summary
Acetylierte Radiata Kiefer, das Produkt einer speziellen Holzmodifikation, besitzt eine verbesserte Dauerhaftigkeit und Formstabilität. Sie ist grundsätzlich für die Herstellung von Brettschichtholz frei bewitterter Konstruktionen geeignet. In der Forschungsarbeit werden entsprechende Kennwerte, die für die Bemessung von Bauteilen und von Verbindungsmitteln erforderlich sind, mit wissenschaftlichen Verfahren hergeleitet.

Summary
Brettsperrholz (CLT) besitzt im Gegensatz zu Brettschichtholz verhältnismäßig hohe Schub- und Querzugfestigkeiten. Bauteile aus CLT sind daher weniger empfindlich gegenüber Rissen und weisen eine größere Robustheit auf. Im Rahmen eines Forschungsvorhabens wurde das Tragverhalten von CLT-Trägern mit Ausklinkungen, Durchbrüchen und Queranschlüssen sowie Trägern mit schräg zur Faserrichtung angeschnittenen Rändern untersucht und Bemessungsansätze für die verschiedenen Trägerformen entwickelt.

Summary
Joints and shear walls of buildings made from dowel-laminated timber were experimentally investigated and assessed. Based on cyclic tests on shear walls, a nonlinear dynamic building model was developed. The developed model served to evaluate the seismic behaviour of buildings made from dowel-laminated timber and to derive a preliminary behaviour factor q required for seismic design of this building typology.
