Wood is a material whose use in constructions has increased in modern times. However, wood is a complex material that needs to be further explored to increase the understanding of its properties. The purpose of this work is to study two positions for attaching a balcony railing regarding different direction of the fibers in the wood. More in-depth this study focuses on identifying the influence of position and fibers on the moment capacity and stiffness. This study concerns unevenly distributed compressive loads perpendicular to the grain of the CLT specimen. Forces that occur on a balcony railing causes a bending moment, which is non-linearly distributed in the contact area between the steel plate and the CLT. The study is performed through experimental tests in a laboratory. Deformations are measured using measuring instruments. The measurements results are analyzed to determine moment capacity and stiffness for the different loading configurations. The conditions for the load vary between across and along the fiber orientation of the top layer of the CLT specimen. The results show that loading configurations with the steel plate attached at the edge of the CLT specimen gives higher moment capacity and stiffness in comparison with connections mounted in the corner. Furthermore, the results also shows that the capacity and stiffness depend on the orientation of the fibers in the CLT deck-layer.
