Cross Laminated Timber (CLT) – Reinforcements with
Self-Tapping Screws
Peter Mestek1, Stefan Winter2
ABSTRACT: This paper illustrates a research project about the calculation and design of Cross Laminated Timber(CLT) elements stressed by concentrated loads. Its focus lies on the shear design of CLT-elements next to punctual supports including reinforcements with self-tapping screws with continuous threads in areas of high shear stresses
Different influencing parameters on the distribution of shear forces next to a punctual support were evaluated by using comparative FEM-analyses. In the course of laboratory tests material-mechanical principles were determined to considerthe interaction of rolling shear stresses and compression perpendicular to the grain. In addition to FEM simulations several experimental tests were carried out to describe the load bearing behavior and the strengthening effect of CLT-elements reinforced by self-tapping screws. The investigations aim at developing a design concept including
the effects mentioned above.
