Abstract

This article presents an analytical approach to determine the load-carrying capacity of timber elements from glued-laminated or cross-laminated timber, featuring shear reinforcements like self-tapping screws. Using matrix format, the approach is based on common theoretical concepts and constitutive equations for material properties. It uses the structural anisotropy of the cross-sections with shear reinforcement, also enabling to incorporate the semi-rigid composite action between the reinforcement and the wood material. The description of the general approach is followed by a comparison with experimental data from tests on both timber products. It is shown that shear reinforcements have a distinct positive influence on cross-laminated timber elements. Shear reinforcement by self-tapping screws in glued-laminated timber elements does in contrast only result in a small increase in shear stiffness and shear strength.
