Summary
In der vorliegenden Arbeit wurden die Anwendungsmöglichkeiten von Biegeträgern aus Brettsperrholz bei Beanspruchung in Plattenebene untersucht. Mit Hilfe numerischer und analytischer Methoden wurden die für die Bemessung von Brettsperrholzträgern erforderlichen Ansätze für den Nachweis der Biege- und der Schubtragfähigkeit sowie zur Berechnung der Verformungen entwickelt und hergeleitet.

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
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
Beams made of cross laminated timber (CLT) offer several advantages over solid or glued laminated timber beams due to their typical layup of orthogonally bonded layers. One major benefit of CLT is the high tensile strength perpendicular to the beam axis making CLT-beams less susceptible to cracks. Therefore, the use of CLT for the production of beams with tensile stresses perpendicular to the beam axis provides a considerably improved robustness. In Europe, the requirements for the production and design of CLT-products are currently governed by technical approvals. However, a draft European standard specifying the performance requirements of cross laminated timber products has already been published in 2011. Although most of today’s CLT-products are very similar in their structure and also efforts are made to develop standardised methods for design and verification of CLT, there is, so far, no general approach for the shear design of CLT-members loaded in plane. In fact, the strength properties and also the design methods given in different technical approvals for the verification of in plane shear stresses vary significantly and, moreover, for most products no information on the shear stiffness in plane direction is given at all. One main reason for the disparities seems to be the more complex calculation of shear stresses and deformations in CLT-members compared to traditional timber materials and therefore, in many cases, vastly simplified methods are used. The intention of the present paper is to contribute to the development of standardised methods for the shear design of CLT-members loaded in plane. Therefore, at first, analytical solutions for the calculation of shear stresses and shear deformations in CLT-beams loaded in plane are presented. The equations are then validated by test results.
