| dc.description.abstract | This thesis presents a comprehensive experimental investigation aimed at gaining a deeper understanding of the shear resistance and failure modes of un-reinforced and reinforced notched Cross-Laminated Timber (CLT) plates. It addresses the limited availability of experimental data on notched CLT by exploring the structural behavior of notched CLT plates with and without reinforcement. A total of 174 CLT plates with various notches and reinforcement using self-tapping screws (STS) were tested in bending in both major and minor strength directions. Un-notched CLT beams under bending primarily failed in rolling shear in the transverse layers. Notches influenced not only the failure mode but also shear resistance and crack propagation. STS effectively increased the shear resistance of notched plates, with inclined screws showing slightly higher resistance compared to vertical screws. By reinforcing the notches located within the lowest transverse layer in CLTs oriented in minor strength direction, shear resistance of the corresponding un-notched plates could be attained. However, for notch ratios above 35% in those CLTs, only approximately half of the un-notched plates' shear resistance could be achieved by reinforcement. The findings offer insights for engineers involved in designing notched and reinforced CLT plates and can contribute towards developing future design guidelines for notched CLT plates. | en_US |
