Structural analysis of in-plane loaded CLT beam with holes: FE-analyses and parameter studies

A major obstacle for developers, producers and designers is the current status of CLT in European product and design standards. A product standard for CLT, EN 16351, has just recently been published but CLT is still not included in the current version of Eurocode 5. There are however some design handbooks available and other technical documentation issued by the producers. The practicing engineer is hence left with a fragmented body of handbooks, European Technical Assessments, research reports, conference proceedings and journal papers for design of CLT-elements. This paper is aimed at giving a considerable contribution to the on-going review process of Eurocode 5, as a background paper regarding CLT- beams with holes and notches. The paper is focused on the numerical analysis of cross- laminated timber (CLT) beams with holes or notches loaded in- plane under various loading conditions. Special emphasis is on shear loading and the in-plane shear behavior considering the complex internal structure of the CLT element. Cross laminated timber presents a much better solution for beams with holes or notches as compared to glued laminated timber thanks to its lay-up: tensile forces perpendicular to the beam axis can be transferred by the transversal layers.
