N2 - This paper is focused on calculation and design methods for Cross Laminated Timber (CLT) elements. The influence of the shear deformation of the cross layers and the resulting consequences to the load bearing behaviour is explained. The main focus lies in the stresses caused by concentrated loads. Normal and shear stress distribution in the area of a concentrated load is calculated and evaluated for uniaxial spanned systems according to the shear analogy and by an FEM-calculation with shell elements. The differences of the results are explained. A simplified method shows how to consider the influence of the shear deformation on the longitudinal strain of a simply supported beam stressed by a concentrated load. Furthermore theoretical considerations and experimental investigations into the twisting stiffness of CLT-elements and its influence on load bearing behaviour are presented.
